Which of the following is BEST thing to do at bidder conference?
a) Answer seller’s questions
b) Meet the seller’s teams
c) Make sure the seller has all the procurement documents
d) Make sure the seller asks all their questions

your views pls.

a) Answer seller’s questions

Because in a Bidder Conference, it is to be made sure that all the seller's questions are answered. This ensures every seller had the same information.

Why not D?

It is also important that seller ask all their question so that they are clear in what they are going to undertake as a part of the contract..?

@ashwin,

you said "This ensures every seller had the same information." means the PM make sure everyone has all procurement docs. then answer is C
