Answer:
The correct answer would be - the child is on a threat of any type of disease especially contagious such as chickenpox.

Children with leukemia are immunosuppressed which means their immune system is not working properly and are prone to any disease that is contagious. Vaccines of the Chickenpox is a live virus that should not be given to any immunosuppressed child.
Meticorten or prednisone does not provide immunity to the chickenpox. A child with the immunosuppressed condition can not live in proximity to the chickenpox patient. Chickenpox is a disease that can be spread by air in the form of small droplets and infect other people.
Thus, the correct answer is - the child is on a threat of any type of disease especially contagious such as chickenpox.
