Explanation / Answer
Correct answer is option B.
In drosophila, the segments are repeating primordial units which are formed on the anterior-posterior axis of the embryo. These segments correspond to the parts of the adult body.Example: Thorasic segment.
Parasegments on the other hand are the fundamental units of embryonic gene expression in Drosophila.
