Correct choice is (a) True

To explain: The helical antenna radiation pattern is a combination of small dipole and loop antenna.If the diameter of the helical antenna is zero (pitch angle 90) then it is linear antenna and when spacing length becomes zero (pitch angle 0) then it acts like a loop antenna.
