I got this question by my school teacher while I was bunking the class.

This interesting question is from Construction of Yagi in section Folded Dipole & Yagi – Uda Antenna of Antennas

Answer 1

Right answer is (a) 0.91

The best explanation: For a 3 element Yagi-Uda array,

Director element length (feet) = 455/f (MHz) = 455/500 = 0.91 feet.
