When a progressive tense is used in the independent clause, the dependent clause typically uses the tense.
simple past

simple present

progressive past

progressive prersent

The correct answer is simple past.

The usual sequence of tenses is that the independent clause will have a progressive/continuous tense, and the dependent clause within it will have a simple tense. For example: He was watching the TV because he wanted to find out what happened in his favorite show.
The first clause is independent, and contains a progressive tense, whereas the second one is dependent, and contains a simple past tense.
