Identify the region 'X', the factor 'Y' and the enzyme 'Z' involved in the process of transcription in prokaryote as shown in the schematic representation given below.

Options :

1. Region 'X' - Terminator Factor 'Y' - Sigma (σ) Enzyme 'Z' - RNA polymerase

2. Region 'X' - Promoter Factor 'Y' - Rho (ρ) Enzyme 'Z' - RNA polymerase

3. Region 'X' - Promoter Factor 'Y' - Sigma (σ) Enzyme 'Z' - RNA polymerase

4. Region 'X' - Promoter Factor 'Y' - Sigma (σ) Enzyme 'Z' - DNA polymerase
