So it's C. rapidamente

When you are telling where, how and the state of someone, examples: yo estoy aqui, that means that I am here and it's telling where I am, ustedes están enfermos, that means that you(plural) are sick, it is telling how you are, it's basically the same as in English, just that in is spanish the verb to be is divided into two meanings, ser/estar
