Solution

The correct option is C Linear
Megaspore mother cell, also called as megasporocyte, undergoes meiosis to form four haploid megaspores. Where present, the wall after the first meiotic division is laid down transversely, forming a dyad. Similarly, the second division in the two dyad cells is transverse. In this way, a linear tetrad of megaspore is formed.
Thus, the correct answer is option C.
