Best answer
Correct option is (c) Chromosome 3 will be inactivated

For explanation: XIC is responsible for silencing one of the X chromosomes in a female for dosage compensation. If an XIC is present within the chromosome 3 it will be considered similar to an X chromosome and it may as well be inactivated.
