Asentence that contains one independent clause and one or more dependent clauses is a simple sentence complex sentence compound sentence fragment

The answer to the question above is "complex sentence".

Explanation:

A complex sentence has one independent clause and least one dependent clause. The difference between an independent clause and a dependent one is that the first one can stand alone as a sentence as it represents a complete thought. For instance, take the following sentence: When the cake is brown, take it out of the oven.

a) *When the cake is brown

b) Take it out of the oven

A can't stand alone as a sentence, it depends on the independent clause (B) to complete its meaning.
