A tape or film that leads to the beginning of a broadcast is called:

(A) initiator

(B) leader

(C) mover

(D) starter

Correct Ans: (B)

Explanation:
Broadcast technicians use a leader tape or film to cue the start of a broadcast. This leader contains essential visual or audio markers, ensuring smooth transitions and precise timing during the broadcast.

The other options describe unrelated terms. An initiator refers to someone or something that starts a process, a mover implies movement, and a starter broadly denotes the beginning of something without specific relation to broadcasting.

The correct answer is leader, as it specifically pertains to the technical setup in broadcasting.
