The correct answer is option 'C' - Fruits.

Explanation:

The joke is a play on words and requires some understanding of puns and wordplay. Let's break it down:

1. The barber: In this context, the barber is a character who typically cuts people's hair and shaves their beards.

2. Want for dessert: The phrase "want for dessert" implies that the barber desires or wishes to have something sweet after a meal.

3. Liquid: Option 'A' suggests that the barber wants a liquid for dessert. While some desserts do contain liquids (e.g., puddings, milkshakes), it is not a specific answer in this context.

4. Juice: Option 'B' suggests that the barber wants juice for dessert. While juice can be a refreshing and sweet beverage, it is not typically considered a dessert on its own.

5. Fruits: Option 'C' suggests that the barber wants fruits for dessert. Fruits are a common choice for desserts as they are naturally sweet, refreshing, and healthy.

6. None of these: Option 'D' implies that none of the given options are correct. However, since option 'C' - Fruits is a valid answer, "None of these" is not the correct choice in this case.

Therefore, the correct answer is option 'C' - Fruits. The joke is intended to be a play on words, where the barber's desire for dessert is humorously contrasted with the expectation of something sweet like fruits instead of traditional desserts like cakes or ice cream.

After the sultan was fed up with the barber he decided to satisfy the barber. So when he asked why are you acting hastily the sultan told that he had invited some friends for a feast. That's when the barber told that he had invited 5 of his friends to dinner and he had not prepared anything .So when the sultan served him the food (as he had not made any preparations for the dinner with his friends)the barber asked the sultan to also give him fruits as dessert.
