Answer 1

The correct option is C Polysomy

Polysomy is a condition found in many species, including fungi, plants, insects, and mammals, in which an organism has at least one more chromosome than normal, i.e., there may be three or more copies of the chromosome rather than the expected two copies.

So, the correct answer is 'Polysomy'.
