Option 3

Explanation:

Ficus benghalensis is commonly called a banyan tree. It is a gymnosperm. The gymnosperms do have non-motile male gametes. The male gametes move towards the micropyle of the ovule of the ovary of a female flower utilizing passive movement.

They don’t have any motile structures attached.  On the other hand, the sphagnum is a bryophyte. The Fucus is an algae, and cycas is an angiosperm. All of them have flagella attached to the sperm facilitating its movement.
