Correct option (b) motile sperms 

Explanation:

Multlciliated motile sperms are found in both Cycas (gymnosperm) and Adiantum or walking fern (pteridophyte). 

Seeds and cambium are present in Cycas (quite common in gymnosperms) but absent in pteridophytes. Vessels are absent in both.

In both Cycas (gymnosperm) and Adiantum (a fern), male gametes are motile. 

Hence, the correct option is (4).
