Which of the following is not a leading urban center in Venezuela?

a. Salvador

b. Maracaibo

c. Valencia

d. Caracas

Macaraibo is a city in Venezuela of 2 million people.

Caracas is the capital of Venezueal - so it's also a leading urban center.

Valencia in Venezuela has almost 2 people - slighly less, so it's an important urban center too.

The correct answer is Salvador: there isn't a big city in Venezuela with this name - and in fact El Salvador is a name of another country.
