The first step of transcription is
A
promotion.
B
elongation.
C
initiation.
D
splicing.
Explanation: 

Detailed explanation-1: -The first stage in transcription initiation is the formation of a complex between the holoenzyme and the DNA sequence at the promoter, which is in the form of a double-stranded DNA.

Detailed explanation-2: -The major steps of transcription are initiation, promoter clearance, elongation, and termination.

Detailed explanation-3: -Initiation. Transcription is catalysed by the enzyme RNA polymerase, which attaches to and moves along the DNA molecule until it recognises a promoter sequence. Elongation. Termination. 5’ Capping. Polyadenylation. Splicing.
