Solution
The correct option is B TATA box
The TATA box is a DNA sequence which is usually found in the promoter region. The segment of DNA involved in transcription is cistron, which has a promoter region where initiation is started. The TATA box is a binding site of general transcription factors or the histone proteins. Tata box is a sequence which is located upstream of the transcription start site.So, the correct option is 'TATA box'
