Explanation:

Question 1

Placing a mesh or cloth screen between light source and subject is to block (stop or reduce) light from reaching the subject. "Screen" is a noun here, "redirect" implies changing direction (not what a mesh/cloth screen primarily does here), "add" is incorrect as the screen doesn't add light.

Question 2

Reflectors work by bouncing (redirecting) existing light to a desired area. "Block" is opposite, "screen" is a noun/action for blocking, "add" is wrong as reflectors don't create new light, just redirect existing.

Question 3

Fill light is defined as the secondary light (supplementary to key light) that fills in shadows on a subject. "Background" light illuminates background, "key" is primary light, "rim" light outlines the subject.

Answer:

B. block
