Solution

The correct option is B $9$ and $22$
The Philadelphia chromosome is a reciprocal translocation involving chromosomes 9 and 22 that is commonly identified in chronic myelogenous leukemia (CML). The break points of the translocation create a fusion of two genes: ABL1 on chromosome 9 and BCR on chromosome 22.

So, the correct answer is '9 and 22'.
