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.
