Muy inteligente. a. eran b. era c. fueron d. fue

Explanation:

The correct answer is B. ERA: Eloisa ERA muy inteligente.

Remember! The way that you conjugate the verb can change the entire meaning of the sentence:

In our example the difference is:

“ERA” is used when you want to express that the action codified by the verb had a duration at the moment that was happening; at this respect, it is different to say:

Eloisa ERA inteligente (she was being intelligent for some time; for example: she was an intelligent woman)

Eloisa FUE inteligente (she was intelligent in a specific moment, for example: she was intelligent in primary school).
