The answer would be A/ along the chang river
The United States didn't want to stay behind, so it increased funding for its own space program in order to be more productive and launch more satellites.<span />
The WPB or War Production Board set the products that would be needed for war and they determined their pricing.
So I agree with you, the answer is A.
But I must admit I was a bit iffy between A and D but I'd still say that A is a better choice.
Hope this helped
