Solution

Female cone of Pinus is a modified long. It occurs on the main stem singly or in pairs. It is homologous to inflorescence of angiosperms. The female cone consists of numerous megasporophylls or female flowers or carpels, which are arranged around the cone axis in a spiral manner. Each megasporophyll is a modified dwarf shoot since it arises in the axil of scaly leaf which is now termed as bract scale. Hence, option B is correct.

Hence, the correct answer is option: 'B'.
