Match Column 1 with Column 2 :

A-ii, B-iii ,C-iv ,D-i

 The correct answer is Option (3) → A-ii, B-iii ,C-iv ,D-i

A. Monoecious - ii. Maize: Monoecious plants have both male and female flowers on the same plant. Example: Maize has separate male (tassel) and female (ear) flowers on the same plant.

B. Dioecious - iii. Date palm: Dioecious plants have separate male and female plants, meaning an individual plant is either male or female. Example: Date palm has separate male and female trees.

C. Cleistogamous - iv. Commelina: Cleistogamous flowers remain closed and ensure self-pollination. Example: Commelina has both cleistogamous (closed, self-pollinating) and chasmogamous (open) flowers.

D. Heterostyly - i. Primula: Heterostyly is a unique form of polymorphism and herkogamy in flowers. In a heterostylous species, two or three morphological types of flowers, termed "morphs", exist in the population. On each individual plant, all flowers share the same morph. The flower morphs differ in the lengths of the pistil and stamens, and these traits are not continuous. Example: Primula exhibits heterostyly.
