<u>Answer:- </u> <em>Option a </em>radial symmetry
<u>Explanation:- </u>
Most of the organisms have can either of the two types of symmetry:-
1. <em>Bilateral symmetry</em>- A body is said to have a bilateral symmetry when it can be divided into 2 equal halves on either side of a <em>single</em> plane.
For e.g if you cut the letter M from middle vertically then you have two equal halves.
2. <em>Radial symmetry</em> - A body is said to be radially symmetrical if it can be divided into similar halves in <em>any</em> plane. This means that the organism has its body parts arranged around a central main axis.
The <em>cnidarians whether in polyp or medusa from exhibit radial symmetry because if you cut them in any plane you will get equal halves.</em>
