B Correct answer
Explanation

It is defined as the step where the amino acid AMP-enzyme complex conjoins with the amino acid binding site of its specific tRNA, where its COOH group bonds with the OH group of the terminal base triplet CCA. This reaction is catalyzed by the same enzyme, aminoacyl tRNA synthetase.
