Match Column-I with Column-II and select the correct option using the codes given below.
Column - I
Column - II
(a) Pistils fused together
(i) Gametogenesis
(b) Formation of gametes
(ii) Pistillate
(c) Hyphae of higher ascomycetes
(iii) Syncarpous
(d) Unisexual female flower
(iv) Dikaryotic

Gametogenesis is the process of formation of male and female gametes (b-i). Pistils are female reproductive organs and have one or more carpels. The presence of fused carpels refers to the syncarpous stage (a-iii). Formation of cytoplasmic bridge facilitates transfer to - strain nucleus into ascogonium and formation of dikaryotic hypha in higher ascomycetes (c-iv). The presence of a unisexual female flower is called pistillate; these flowers lack stamen (d-ii). Therefore, the correct answer is option B.
