Laser gyros have
- no rotating parts.
- moving parts.
- a spinning rotor.
Explanation from PART66Online
A laser (ring laser) gyro detects rotation optically from counter-propagating laser beams and contains no spinning rotor or other moving mechanical parts. This solid-state construction is one of its main advantages, eliminating wear and bearing friction associated with conventional spinning-mass gyros.

may be it is wrong ,since nothing moves except beam of light which is weightless

Hey.
Laser gyros have moving parts, it is correct. Please check this: en.wikipedia.org/wiki/Inertial_naviga...
Lasers gyros have piezo-electric dither motor.

harbhla is right.laser ring gyros ae not in fact gyros,but sensorsof angular rate of rotationabout a single axis.they are made of a triangular block of temperature stable glass.very small tunnels are precisely drilled parallel to the perimeter of the triangle , and reflecting mirrors are placed in each corner.a small charge of Helium-neon gas is inserted and sealed into an aperture in the glass at the base of the triangle.......thus,laser gyros have no moving parts,A is the right answer..

i think a is the correct.Also wikepidia is not a textbook so i wouldnt recommend it.

My bad my academy's textbook clearly states that "a laser gyro has no moving parts " . So whoever sees this know it. This answer in this question is wrong. The a option is the correct.
