A theatrical productions lighting and electronics are run through the

A. Gobos

B. Lighting board

C. Frensel

D. Ellipsodidal reflector

The lighting board makes the most sense because its controlled by the electrician. The gobos is a dark plate or screen used over the light. A ellipsodial reflector is a light control device and a frensel is a special type of lens so B makes the most sense.

I would say B lighting Board
