The correct answer here is C.  The increase in government spending that you refer to here will, in the circumstances described, lead to an increase of $71.42 million in real Gross Domestic Product.

This result can be found by using the spending multiplier.  The relevant equation in this case is

Multiplier = 1/marginal propensity to save

In this case, the MPS is .07.  1/.07 gives us 14.286.  Thus the multiplier for any government spending in this situation is 14.286. 

To find the answer to this question, then, we simply calculate $5 million x 14.286.  This gives us $71.42 million.  Therefore, C is the correct answer.
