The correct answer is option B. "The tRNA that was in the A site moves into the P site".

Once the first codon has been translated into the first amino acid, The tRNA that was in the A site moves into the P-site (peptidyl). The P-site is the second binding site for the tRNA, and the location at which all the following amino acids are added.
