Aresponsibility of the vice president is
a)to declare war if necessary.
b)to join the house if necessary.
c)to join the supreme court if necessary.
d)to become president if necessary.

The correct answer is alternative D) "To become president if necessary"

The Vice-president is elected alongside the President, and his duty is to assist the president, as well as take his place, if necessary. This can happen, for example, when the president has to take care of international affairs in other countries, the vice-president can take care of his domestic agenda, attending his appointments.

If something happens to the president, or if he gets impeached, for example, the Vice-President becomes the acting President.
