Question

No ____ portándose mal en el salón de clases. a. estén b. dé c. sea

Answer 1

No estén portándose mal en el salón de clases

Answer 2

Right answer:

a. estén

The sentence No estén portándose mal en el salón de clases is given in the imperative mood. We use this mood to tell someone to do something in a direct manner. Put another way, sentences in the imperative mood are commands. Perhaps the speaker of this sentence is a teacher that tells his/her students not to misbehave in classes.
