b.

c.
Bertie had several people working for him: a private secretary, an administrative assistant, and a research aide.

Answer 1

answer is c

Step-by-step explanation:

for a, A semicolon is used to join two related clauses in place of a comma so it's wrong.

for b, a comma is used to separate words or sentences, so it's not the best in this context.

c is the best option because: A colon is the best in this case because it is used to show the thing listed under a subject matter.
