Respuesta :
D and A; three quarters is just three quarters, it's plural. A half-cup is singular... I can't explain this very well but hopefully this helps a bit.
Answer:
D. Three Quarters
Explanation:
Since the fraction is used as a noun, there should be no hyphen.
If the fraction were to be used as an adjective, then there should be a hyphen.
Example of a fraction used as an adjective:
We should use one-quarter cup.
