Which of the following statement is true?
A) PAM matrices are derived from an evolutionary model whereas the BLOSUM matrices consist of entirely direct observations. 
B) Because of BLOSUM matrices have less evolutionary meaning that is why the PAM matrices are used most often for reconstructing phylogenetic trees.
C) BLOSUM matrices are entirely derived from local sequence alignments of conserved sequence blocks, whereas the PAM matrix is based on the global alignment of full-length sequences.
D) BLOSUM matrices are more advantageous in searching databases and finding conserved domains in proteins.
