Bourden tube is a sensing elements and so according to variation in pressure it will expand or contract and pointer is connected to the bourden tube so it will indicates the changes in process parameter. So bourden tube and pointer both are functioning at same time so both answer are correct.

I think the bulb will be the primary functioning element which then expands the bourden tube then comes the pointer which is a variable conversion element.

Bourdon tube is functioning element in my opinion, since it is the sensing element.

Pointer could not be pressure sensing element, it only acts as an indicator.
