Answer:
The correct answer is letter "B": to guide the team that will carry out their vision.
Explanation:
Parallel structure is used in writing when the author wants to give two or more ideas the same importance. It is also a tool that adds clarity to the writing so it can be read easily.
In the case given, instead of saying:
"...guiding the team that will carry out their vision..."
It is better to use the infinitive to guide so both verbs guide and carry have the same grammar structure.
