@Nishanjali the correct ans of your question is b.

Sporophyte of gymnosperms is not always heterosporous. It can be homosporous also in case of dioecious plants. For example, in Cycas we have microspore and megaspores on different sporophytic plants while in Pinus single sporophytic plant bears both microspores and megaspores.
