Answer:

Option: B is the correct answer.

( B) AC and BD be the diagonals of a parallelogram ).

Step-by-step explanation:

The best choice for the first line in the proof:

Gerard is trying to prove that the diagonals in any parallelogram bisect each other.

so for the proof of anything we have to firstly write the information given to us.

so in the following proof we have to assume that AC and BD be the diagonals of a parallelogram and later work on it to prove the asked expression.

Hence option B is correct.
