Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Stele with a network of vascular strands, which appear as circular in cross section is called as dictyostele. It is seen in Pteris.
The stellar organisation varies from species to species of Pteris. In the dictyostele of P. vittata, the vascular strands are in the form of a ring and each strand is called as meristele.
Thus, the correct answer is option C.
