d.
a vacancy is filled when a new leader is elected.

The correct option is B

A primary election (primary of nomination), or simply primary, is a choice in which the voters under a jurisdiction select the candidate that a party will present to a later public election. In other words, it is a democratic way of pre-selecting the candidate that a party will present to a certain electoral process. The "Primaries" are more common in the United States, not only for the presidential elections but also to choose the candidates for representatives, senators, mayors and governors, among others, and their origins go back to the progressive movement.
