The correct answer is ethnic.
Explanation:
The sentence requires a word that describes the type of cuisine. "Ethnic" refers to cuisines that are characteristic of a particular culture or region. Therefore, "Indian is one of the most popular ethnic cuisines in the UK" makes the most sense.
Let's look at why the other options aren't suitable:
* goods: Refers to products or merchandise, not cuisine.
* choose: A verb, not a noun describing cuisine.
* takeaway: Refers to food that is purchased to be eaten elsewhere, not the type of cuisine.
* serve: A verb, not a noun describing cuisine.
* multi-cultural: While the UK is multi-cultural, this doesn't directly describe the cuisine itself.
* grab: A verb meaning to quickly take something.
* side: Refers to a dish served alongside the main course.
* taste: Refers to the sensation of flavor.
* dish: A general term for a prepared food, but "ethnic" is more specific and fitting.
