Read the assertion and reason carefully to mark the correct option out of the option given below:
Assertion: Arachidic acid is an unsaturated fatty acid
Reason: There are present one or more double bods between carbon atoms in unsaturated fatty acid

Options

A. if both are true with reason being correct explanation
B. both true but reason is not correct explanation
C. assertion true but reason is wrong
D. and both are wrong

Answer

To solve the assertion and reason question, we need to evaluate both the assertion and the reason provided:

### Step 1: Analyze the Assertion
The assertion states: "Arachidic acid is an unsaturated fatty acid."
- Arachidic acid is actually a saturated fatty acid, which means it contains only single bonds between carbon atoms. Therefore, this assertion is **false**.

### Step 2: Analyze the Reason
The reason states: "There are present one or more double bonds between carbon atoms in unsaturated fatty acid."
- This statement is true. Unsaturated fatty acids do indeed contain one or more double bonds between carbon atoms.

### Step 3: Determine the Relationship Between Assertion and Reason
- Since the assertion is false and the reason is true, we conclude that the reason does not provide a true explanation for the assertion.

### Conclusion
Both the assertion and reason are evaluated as follows:
- Assertion: False
- Reason: True

### Final Answer
The correct option is that the assertion is false, and the reason is true.
