The correct option is C One
In Equisteum (pteridophyte) the female gametophyte is not retained on the parent sporophyte. Hence statement 1 is incorrect.
In Ginkgo (gymnosperm) female gametophyte is dependent on the sporophyte. Hence statement 2 is incorrect.
The sporophyte of Polytrichum (moss) is more developed than that of Riccia (liverwort). Hence statement 3 is correct.
Sexual reproduction in Volvox is oogamous. Hence statement 4 is incorrect.
Therefore, only one statement is correct.
