Core promoter is the site that stretches between _______________

A. TATA box and start site

B. TATA box and stop site

C. TATA box and operator

D. TATA box and the promoter

I have been asked this question in a national level competition.

This question is from Gene Expression Control topic in section Control of Gene Expression of Cell Biology

Right option is A. TATA box and start site

To elaborate: Core promoter is the region upstream of a gene that stretches between the TATA box and the transcription start site. It is the site of assembly for pre-initiation complex consisting of RNA polymerase II and general transcription factors that are required for eukaryotic gene transcription.
