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
Hey there!

The formula for the discriminant is represented by b²-4ac.
We need to identify the values for a, b, and c.
This equation is in general form, which is ax² + bx + c = 0.
So, a = -2, b = -1, and c = -1.
Plug the values into the formula.
(-1)²-4(-2)(-1)
Square.
1-4(-2)(-1)
Multiply.
1-4(2)
1-8
Subtract.
-7
The discriminant is -7.
This means there are no real solutions to the equation, because the discriminant is negative.
Hope this helps!
