Answer:
The correct option is lac operon will function normally.
Step-by-step explanation:
The promoter region can be described as a region due to which transcription begins for a certain gene. Promoters can be present near to the gene for which they initiate transcription or they might be present several sequences away upstream.
The promoter region will still be able to initiate transcription several base pairs away hence the lac operon will function normally. The repressor will also detect the promoter and function normally.
