The correct Answer is:
To solve the assertion and reason question, we will analyze both statements step by step. ### Step 1: Analyze the Assertion - **Assertion**: "Most of the contents of the primary oocyte are retained by the ovum and is much larger than spermatozoon." - **Explanation**: The primary oocyte undergoes meiosis to form an ovum (egg) and polar bodies. The ovum retains most of the cytoplasm and organelles from the primary oocyte, which is why it is significantly larger than the spermatozoon (sperm cell). Therefore, the assertion is **true**. ### Step 2: Analyze the Reason - **Reason**: "Ovum needs energy to go about in search of spermatozoa." - **Explanation**: This statement is misleading. The ovum does not actively move in search of spermatozoa; instead, it is typically stationary within the female reproductive tract. The ovum does require energy for metabolic processes, but it does not "search" for sperm. Therefore, the reason is **false**. ### Step 3: Determine the Relationship Between Assertion and Reason - Since the assertion is true and the reason is false, we conclude that the correct relationship is: - Assertion is true. - Reason is false. ### Step 4: Choose the Correct Option - Based on the analysis, the correct option is: - **Option C**: "If assertion is true and reason is false." ### Final Answer The correct answer is **Option C**. ---

Assertion A block of mass m starts moving on a rough horizontal surface with a velocity v. It stops due to friction between the block and the surface after moving through a certain distance. The surface is now tilted to an angle of 30^(@) with the horizontal and the same block is made to go up on the surface with the same initial velocity v. The decrease in the mechanical energy in the second situation is smaller than that in the first situation. Reason The coefficient of friction between the block and the surface decreases with the increase in the anglle of inclination.
