The correct answer is: C. Either I or II is implicit
The statement says that the Ministry has announced an economic package to support the voluntary organisations. This does not mean that voluntary organisations do not need such support, nor does it mean that the government was not supporting them earlier. It is possible that the government has been supporting voluntary organisations in the past, but that the new economic package is a way of increasing that support. It is also possible that the government has not been supporting voluntary organisations in the past, and that the new economic package is a way of starting to do so.
Therefore, either assumption I or assumption II could be implicit in the statement.
