Assertion : Ribs are thin, flat and curved bones that form a protective cage around some internal organs of the body.
Reason : All the 24 ribs are attached to the backbone at the back and to the breastbone in the front.

A

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion:** - The assertion states that "Ribs are thin, flat and curved bones that form a protective cage around some internal organs of the body." - This statement is true because ribs do indeed protect vital organs like the heart and lungs. 2. **Understanding the Reason:** - The reason provided is "All the 24 ribs are attached to the backbone at the back and to the breastbone in the front." - This statement is partially true but misleading. While it is correct that there are 24 ribs (12 pairs), not all of them attach to the breastbone. Only the first 7 pairs (true ribs) are directly attached to the breastbone. 3. **Analyzing the Statements:** - Since the assertion is true and the reason is false, we need to determine the correct option based on this analysis. 4. **Choosing the Correct Option:** - Based on the evaluation, the correct option is C: "If assertion is true but reason is false." **Final Answer:** The correct option is C. ---

Assertion: Carvial vertebrae, ribs and sternum together form the rib cage. Reason: The bones of the limbs along with the girdles constitute the axial skeleton.

Read the passage given below and answer the question: The transition metals when exposed to oxygen at low and intermediate temperatures form thin, protective oxide films of up to some thousands of Angstroms in thickness. Transition metal oxides lie between the extremes of ionic and covalent binary compounds formed by elements from the left or right side of the periodic table. They range from metallic to semiconducting and deviate by both large and small degrees from stoichiometry. Since d- electron bonding levels are involved, the cations exist in various valence states and hence give rise to a large number of oxides. The crystal structures are often classified by considering a cubic or hexagonal close-packed lattice of one set of ions with the other set of ions filling the octahedral or tetrahedral interstices. The actual oxide structures, however, generally show departures from such regular arrays due in part to distortions caused by packing of ions of different size and to ligand field effects. These distortions depend not only on the number of d-electrons but also on the valence and the position of the transition metal in a period or group. (source: Smeltzer, W. W., & Young, D. J. (1975). Oxidation properties of transition metals. Progress in Solid State Chemistry, 10, 17-54.) In the following question, a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the choices on the basis of the above passage. Assertion: CrO crystallises in a hexagonal close-packed array of oxide ions with two out of every three octahedral holes occupied by chromium ions. Reason: Transition metal oxide may be hexagonal close-packed lattice of oxide ions with metal ions filling the octahedral voids.
