The correct answer is A.
AIDS has been most devastating to underdeveloped regions of the world because of poverty.
Inadequate diet, poor health and having insufficient income to buy contraceptives all played a major role in the spread of the disease in poor regions of the world.
A lack of education is big factor as well. Mothers are unaware of the risks of passing the infection to their children, many can not read and can not use medicaments in the correct way. Access to clean, unpolluted water is often restricted too, which contributes to the spread of AIDS.
The lack of adequate healthcare and information in underdeveloped regions of the world are the major risks and factors that led to development and spread of this deadly virus infection there.
