The correct option is
D Generous
The correct answer is Option C.
PARSIMONIOUS means someone who is not willing to spend money or use resources.
GENEROUS is the opposite of the word because it means someone who is ready to spend money and use resources.
The remaining options are incorrect because:
ILLIBERAL means restrictive.
CRUDE means unrefined and in a raw state.
STINGY means someone who does not use money or resources freely.
