- B.China rose and citrus
- C.China rose

Correct Answer
(A) Pea
Solution & Explanation
Diadelphous means the stamens are united into two separate bundles. The classic NCERT example is the pea flower, where 9 stamens fuse into one bundle and 1 stamen stays free (9)+1. China rose is monadelphous (one bundle) and citrus is polyadelphous (more than two bundles), so the only correct choice is Pea. NCERT Reference: Ch 5, p.64, lines 33-35 — "or two bundles (diadelphous) as in pea, or into more than two bundles"
