He has lost . . . . . . rupees in gambling. Now, he lives like a beggar.

The correct answer is Option B: a few.

Let's understand why:

1. The word "rupees" is a plural countable noun. This means you can count rupees individually (one rupee, two rupees, many rupees).

2. "a few" is used with plural countable nouns to mean "some" or "a small number". For example, you would say "a few books" or "a few friends." Since "rupees" is a plural countable noun, "a few" fits grammatically in the sentence.

3. Let's look at why the other options are incorrect:
* Option A: "a little" is used with uncountable nouns. These are things you cannot count individually, like water, sugar, or "money" when referring to the general concept or substance. You would say "a little water" or "a little patience." Since "rupees" are countable, "a little" is incorrect here.
* Option C: "a some" is grammatically incorrect in English. We use "some" by itself (e.g., "some rupees") or other quantifiers, but never "a some."
* Option D: "All" is incorrect because only one of the options (A, B, or C) is the right answer.

Therefore, among the given choices, "a few" is the only grammatically correct option that can be used before the plural countable noun "rupees." The sentence "Now, he lives like a beggar" emphasizes the severe consequence of his loss, but the blank needs a quantifier that properly modifies "rupees."
