Question

Fill in the blank with the correct form of "Ser" or "estar". Los niños _____ alegres. Option 1: son Option 2: están Option 3: sea Option 4: estén

Answer 1

Option 2: Estan

Step-by-step explanation:

Being happy is temporary. This means that the verb would have to be estar, not ser. Then, to conjugate estar for the "ellos" form, because "los ninos" is plural, you would change the ending to -an. So, the correct verb to fill in the blank is estar.
