b. because too much noise makes mrs. van daan nervous.
c. because they don't want the workers in the building to hear them.
d. because the nazis ordered all jews to be quiet during the day.

The correct answer is c. Because they don't want the workers in the building to hear them.

Explanation: The reason for this is because while the families were in hiding, there were people working in the factory during the day. If they made any noise during the day they could risk giving away their hiding spot, be found, and taken away to a concentration camp where they would most likely die.
