Second heart sound (S2) is produced due to closure of:

Correct option is B, Semilunar valves. In Cardiac Cycle and Regulation, the accurate description is Semilunar valves, and that is what you should commit to memory. Keep the definition tight and the role clear — cause and effect line up with Semilunar valves — that is the mechanism or reason the stem is pointing to. Then Semilunar valves is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Semilunar valves.

Ref: Animal physiology is Unit 7 of the CSIR NET Life Science Syllabus, covering core body systems. It accounts for roughly 10% of the total marks in Sections B and C.

Type 1 diabetes mellitus is caused by destruction of:

Go with B — Beta cells. Within Endocrinology, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, cause and effect line up with Beta cells — that is the mechanism or reason the stem is pointing to. Holding that picture in mind makes Beta cells feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Beta cells.
