Right answer is (a) True

To explain I would say: A choke is a restriction which controls the rate of liquid metal flow. It prevents the molten metal to enter the mould in the form of a jet and thus minimizes sand erosion. Hence, in a gate with skim bob and choke a choke is provided a choke in between in-gate.
