Correct Option: B

Aneuploidy is an error in cell division that results in the daughter cells having the wrong number of chromosomes. It is the second major category of chromosomes mutation in which chromosome number is abnormal. An aneuploid is an individual organism whose chromosome number differs from the wild type by part of a chromosome set. Generally, the aneuploid chromosome set differs from wild type by one or small number of chromosomes. Aneuploids have chromosome number either greater or smaller than of wild type. Aneuploid nomenclature is based on the number of copies of the specific chromosome in the aneuploid state. So, for drosophila with 16 chromosomes, it is not aneuploid in condition. ​
