which of these is a trna?

Transfer RNA (tRNA) is a small RNA molecule that carries specific amino acids to the ribosome and has an anticodon region that pairs with codons on mRNA during protein synthesis. Without seeing the actual answer choices, the tRNA option would be the one described as an adaptor that links mRNA codons to the correct amino acids, typically a cloverleaf‑shaped RNA of about 70–90 nucleotides with an anticodon and an amino acid attachment site.
