The right answer is The lac operon would be transcribed constitutively.
An operator is a nucleic acid segment to which a regulatory protein that modulates downstream gene expression is bound. it can either stimulate or inhibit the production of the gene product thus controlled.
If the operator is absent, there will be no more regulation of the operon, so the transcription of the operon will not be regulated, and the synthesis will be continuous and constitutive.
