He has ___________ rupees in his wallet.

The correct answer is A: a few. This question assesses your understanding of quantifiers, specifically the difference between "a few" and "few," and "a little" and "little." These quantifiers are used with countable and uncountable nouns to express quantity.

The noun "rupees" is a countable noun (you can count individual rupees). Therefore, we must use quantifiers that are appropriate for countable nouns, which are "a few" or "few."

• A: a few means "some" or "a small number." It implies a positive quantity, suggesting he has some rupees, enough to be mentioned. This fits the common context of having money in a wallet.
• B: few means "almost none" or "not many." It carries a negative connotation, implying a lack of rupees. While grammatically possible, "He has few rupees" would suggest he has barely any, which might not be the intended meaning unless specified. However, "a few" is the more neutral and common choice when simply stating presence of some countable items.
• C: little and D: a little are incorrect because they are used with uncountable nouns (e.g., "little water," "a little time"). "Rupees" is countable.

Given the options, "a few" is the most appropriate choice to indicate a small but present number of rupees.
