Solution
The correct option is C Trp
Trp(tryptophan) operon is an anabolic operon found in E. coli as it codes for the enzymes that help in the synthesis of the amino acid tryptophan. The trp operon is expressed (turned on) when tryptophan levels are low and repressed (turned off) when they are high. The trp operon is regulated by the trp repressor.
Lac operon and Ara(L-arabinose) operon are catabolic operons, as they synthesise enzymes which helps the E. coli to breakdown the respective sugars into simpler forms.
