Which is the right answer
Adverbial Clauses Of Concession

It's a very hot place.

Explanation:

The above answer is correct.

An adverbial clause of concession is a statement which actually expresses an idea that shows or suggests the opposite of what the main part of the sentence is saying. It is a clause which begins with conjunctions like "though", "although" or "even though" which contrasts with the main idea.

Adverbial clauses of concession are usually introduced by subordinating conjunctions like though, although, even though, even if, while and whereas.

From the the given sentence:

Valledupar is a very beautiful city, though it's a very hot place.

We can see that the clause that follows after though suggests the opposite of the main statement that says, Valledupar is a very beautiful city.

The above answer is correct.
