Give below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
| Assertion (A): | In human beings, insulin is synthesized as a pro-hormone which needs to be processed before it becomes fully mature and functional. |
| Reason (R): | The extra stretch of C-peptide is to be removed from A and B peptide chain of insulin. |
In the light of the above statements, Choose the most appropriate answer from the option given below :
| 1. | (A) is correct but (R) is not correct. |
| 2. | (A) is not correct but (R) is correct. |
| 3. | Both (A) and (R) are correct and (R) is the correct explanation of (A). |
| 4. | Both (A) and (R) are correct but (R) is not the correct explanation of (A). |
