President pro tempore of the senate can best be described as
a)the highest position in the senate.
b)the most powerful position in the senate.
c)having some power, but less than the majority leader.
d)a largely ceremonial role without much power.

C)having some power, but less than the majority leader.

Explanation:

President pro tempore is the second highest position in the senate, because the highest position as the leader of the senate is held by the vice president of united states. (this eliminates options A and B)

President pro tempore will act as a direct right hand of the vice president and able to represent the vice president in case of absence. Because of this, we can say the president pro tempore has a pretty large power within the senate (this eliminate option D)
