Solution

The correct option is A It has circinate vernation
the fern frond is tightly curled so that the tender growing tip of the frond (and each subdivision of the frond) is protected within a coil. The emerging of fern frond is called as circinate vernation which is absent in Cycas. In cycas xylem vessels found in the xylem and roots contain ball grid array, cycas does not have a well organized female flower.
So the correct option is 'It has circinate vernation.'
