The correct answer is: C. Either I or II is implicit
The statement says that the World Health Organisation has decided to double its assistance to various health programmes in India. This suggests that the WHO believes that its current assistance is not enough to meet the health needs of the Indian population. This, in turn, suggests that the government funding for health in India is less than adequate.
However, the statement does not explicitly say that the government funding is less than adequate. It is also possible that the WHO believes that its current assistance is not enough to meet the health needs of the Indian population because the per-capita expenditure on health in India is very low compared to many other countries.
Therefore, either assumption I or assumption II is implicit in the statement.
