The Flies with Variegated Eye Color Had What Abnormal Chromosome

The flies with variegated eye color had what abnormal chromosome structure?

A) X-chromosome inversion that moves the w⁺ gene to a different orientation on the chromosome in some cells following X-ray exposure
B) X-chromosome translocation that moves the w⁺ gene to a region of heterochromatin on another chromosome in some cells following X-ray exposure
C) a mutation in the w⁺ gene following X-ray exposure that causes the gene to be overexpressed in a tissue-specific manner
D) X-chromosome deletion that deleted the w⁺ gene in some cells following X-ray exposure
E) a mutation in a somatic chromosome that causes the w⁺ gene to be translocated to the X-chromosomes following X-ray exposure
