d. | Insulin from an animal source may cause allergy or other types of reactions in some diabetic patients. |
Assertion (A): | Insulin used for diabetes was earlier extracted from the pancreas of slaughtered cattle and pigs but now it is not used. |
Reason (R): | Aarti along with some other patients took insulin injections in which insulin was from an animal source and they manifested an allergic response to that. |
