Final Answer :
B
Explanation :
Cri du chat syndrome is caused by a deletion of a part of chromosome 5, specifically on the short arm of the chromosome (5p-). This deletion leads to the characteristic symptoms of the syndrome, including a high-pitched cry that resembles a cat's cry, which is where the name "cri du chat" (cry of the cat) comes from.
