Given below are two statements: 
Statement I: An alignment is generated by starting at the ends of the two sequences and attempting to match all possible pairs of characters between the sequences and by following a scoring scheme for matches, mismatches, and gaps. Statement II: For proteins, an amino acid substitution matrix, such as the Dalhoff percent accepted mutation matrix 250 (PAM250) or Blossom substitution matrix 62 (BLOSUM62) is used to score matches and mismatches. 
In the light of the above statements, choose the most appropriate answer from the options given below:
