A)The RNA base sequence determines the DNA base sequence which, in turn, determines the protein amino acid sequence.
B)The DNA base sequence determines the RNA base sequence which, in turn, determines the protein amino acid sequence.
C)The DNA base sequence determines the protein amino acid sequence which, in turn, determines the RNA base sequence.

The DNA base sequence contains the code for the RNA base sequence through transcription. The RNA base sequence is then used during translation to determine the order of amino acids in the protein. Therefore, the correct sequence is DNA → RNA → protein.
