Detailed explanation-1: -So, the correct answer is “ carpel ".

Detailed explanation-2: -The megasporophyll of gymnosperms bears megasporangia, a female gamete. On the contrary, in angiosperms or seed plants, the female gametophyte is produced in the megasporangium. Moreover, fertilization and embryo formation also occur there. Therefore, the megasporophyll in angiosperms is rolled to produce a carpel.

Detailed explanation-3: -In gymnosperms male gametes are produced in microsporophyll, hence they perform the role of the stamen of flowers. On the other hand, female gametes are produced by the megasporophyll and they are therefore analogous to the pistil/carpel of flowers.

Detailed explanation-4: -Megasporophyll is the term used in gymnosperm to denote carpel (female reproductive organ). The megasporophylls are loosely arranged in Cycas. They do not form a true female cone. Female reproductive structure is a rosette of megasporophylls arising spirally in acropetal succession on the stem apex of female plant.

Detailed explanation-5: -Megasporophyll of cycas is present on the female plants which produce ovules. The carpel is a female reproductive organ of a flowering plant.
