Correct option is (a) True

For explanation: In Francis turbine, the water enters radially inward but leaves in a parallel direction to the shaft at the center, it is called mixed flow. In the case of a reaction turbine like Francis turbine, a draft tube is used to connect the outlets of the runner to the tailrace.
