Assertion (A): Unsaturated fats are more reactive compared with the saturated fats. Reason (R): Unsaturated fats have only single bonds in their structure.

1. This is an Assertion-Reason question comparing unsaturated fats and saturated fats. 2. Assertion (A): Unsaturated fats are more reactive compared with the saturated fats. This is true. Unsaturated fats contain one or more double or triple carbon-carbon bonds. These double/triple bonds are sites of higher electron density and are more susceptible to chemical reactions (like addition reactions, oxidation) compared to the single bonds found in saturated fats. 3. Reason (R): Unsaturated fats have only single bonds in their structure. This is false. The defining feature of unsaturated fats is the presence of at least one carbon-carbon *double* or *triple* bond. Saturated fats are the ones that have only single bonds. 4. Since Assertion (A) is true and Reason (R) is false, the correct option is (C).
