The president vetoes a bill proposed to become law by congress. in this situation, what is the purpose of this power?

a. to limit the power of the legislative branch
b. to replace the power of the legislative branch
c. to strengthen the power of the legislative branch
d. to remove the power of the legislative branch

A. limit the power of the legislative branch
It is not B. because the president cannot then go on to make a law by himself(though executive actions are kind of similar but for these purposes it is not relevant)
It is not C because it clearly does not strengthen the power of the legislative branch
It is not D because the legislative branch can still overturn the veto with a 2/3 vote so a veto does not remove the power of the legislative branch
