E.translocation

Explanation:

The chromosomal disorder CML is caused by reciprocal translocation between chromosome 9 and chromosome 22, in which rearrangement of chromosomes takes place.

Due to this rearrangement, part of chromosome 9 having ABL1 gene gets fused with part of chromosome 22 having BCR gene and resulting chromosome is known as Philadelphia chromosome.

ABL1-BCR fusion gene represents an oncogene that codes for a mutated protein that leads to unregulated cell division and impaired DNA binding and can cause cancer.
