All the choices contribute to the attenuation of the trp mRNA transcript. High levels of tryptophan lead to the activation of the trp operon's attenuation mechanism. Plentiful amounts of trp tRNA allow for the uninterrupted synthesis of the leader peptide, which is crucial for the formation of the stem-loop structure at the 5' end of the attenuator region, ultimately leading to the termination of transcription.
