Answer:
A-carries an amino acid to its correct codon.
Step-by-step explanation:
Transfer RNA (tRNA) carries amino acids to the ribosome, where they are added to the growing protein chain. Each tRNA has an anticodon that matches a specific codon on the mRNA. The tRNA with the matching anticodon binds to the mRNA codon, and the amino acid it carries is added to the growing protein chain. Therefore, option A is correct.
