—¿cómo está sr. ruiz? —muy bien, gracias.

a. igualmente
b. encantado
c. ud.

Usted. Would be the answer. The question asks how are you? Usted is a formal way of addressing someone.

Igualmente means the same.

Encantado means it was a pleasure to meet you,

The answer would be ellas (if they are both girls if not use ellos)    van a ( whereever they're going) for example: ellos/ ellas van a el cine
