This is the only choice that mentions bouncing signals off walls and ceilings, and it specifically mentions its use with TV remotes. Laser and narrowband radio do not typically bounce off walls and ceilings, and microwave frequencies are typically used for long-range communication rather than for short-range applications like TV remotes.
