Solution
The correct option is C Monosomic
Monosomy is the absence of a single chromosome from a diploid cell (2n-1). Changes in chromosome number by additions or deletions of less than a whole set is called aneuploidy. The gametic cell has half the chromosome content as that of the somatic cell of same species. Polyploidy refers to the presence of more than two sets of chromosomes; diploid organism having multiples of 2n genome is polyploid. The Presence of one chromosome in triplicate (2n+1) is called trisomy. Thus, the correct answer is option C.
