Which will it be

Fruit and vegetable store
--------------------------------

Seller: What would you like? Fruit? Vegetables?
Boy: Ah, yes, please.
Seller: So, which will it be? Fruit or vegetables?
Boy: Fruit and vegetables.
Seller: Very well, which fruit would you like?

--------------------------------------------------

What does "which will it be? mean?

Does it mean "which would you like?"?

Thank you
