The correct answer is: B. Only assumption II is implicit
The statement says that providing mid-day meals to children in primary schools will increase the number of students attending schools. This means that some children are not attending school because they do not have enough to eat. Providing mid-day meals will address this problem and encourage these children to attend school.
Assumption I is that mid-day meals will attract the children to the schools. This is not necessarily true. Some children may not be interested in mid-day meals, or they may already have enough to eat. Even if mid-day meals do attract some children to school, it is not clear that this will lead to an increase in the overall number of students attending school.
Assumption II is that those children who are otherwise deprived of good food will attend the schools. This is a more likely assumption. If children are not getting enough to eat at home, they may be more likely to attend school if they know that they will get a good meal there. This assumption is consistent with the statement, and it is likely to lead to an increase in the number of students attending school.
Therefore, only assumption II is implicit in the statement.
