The Answer is D : When tryptophan is present at high concentrations, the repressor binds to the operator and transcription is initiated and not terminated.

Statements about the mechanism of attenuation is true is c. When tryptophan levels exist low, a transcription exists initiated and continues through the leader province into the structural genes, resulting in the presentation of a polytheistic mRNA and, eventually, the enzymes needed for the biosynthesis of tryptophan.
What is mechanism of attenuation?
In genetics, attenuation exists as a proposed mechanism of authority in some bacterial operons which results in premature termination of transcription and exists founded on the fact that in bacteria, transcription, and translation proceed simultaneously.
Tryptophan exists as an amino acid required for normal growth in infants and the presentation and maintenance of the body's proteins, muscles, enzymes, and neurotransmitters. It exists as a critical amino acid. This indicates your body cannot produce it, so you must obtain it from your diet.
In physics, attenuation or, in some contexts, extinction exists as the gradual loss of flux intensity via a medium. For example, dark glasses attenuate sunlight, lead attenuates X-rays, and water and air attenuate both light and sound at varying attenuation rates.
Hence, Statements about the mechanism of attenuation is true is c. When tryptophan levels exist low, a transcription exists initiated and continues through the leader province into the structural genes, resulting in the presentation of a polytheistic mRNA and, eventually, the enzymes needed for the biosynthesis of tryptophan.
