Answer & Solution

Correct Answer

(D) (A) - (ii), (B) - (iii), (C) - (v), (D) - (iv)

Step-by-step Solution

Detailed explanation

(d) : Synapsis aligns homologous chromosomes-Zygotene
Synthesis of \(RNA\) and protein -\(G_2\) phase
Action of enzyme recombinase -Pachytene
Centromeres do not separate but chromatidsmove towards opposite poles -Anaphase \(I\)

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.

Same subject

Match List \(I\) with List \(II\).

List \(I\)	List \(II\)
(A). Mast cells	(I). Ciliated epithelium
(B). Inner surface of bronchiole	(II). Areolar connective tissue
(C). Blood	(III). Cuboidal epithelium
(D). Tubular parts of nephron	(IV). Specialised connective tissue
