Solution
The correct option is B Duchenne muscular dystrophy
Duchenne's muscular dystrophy is a genetic disorder seen on the X chromosome. It is due to a mutation in the gene that codes for a protein called Dystrophin which is an important structural component of muscle. Without muscles become weak, and eventually paralyzed. This disease affects primarily boys as they have only one X chromosome. Eventually, the disease affects the respiratory muscles and these boys die due to paralysis of respiratory muscles.
