A
Only 2 and 3
💡 Explanation:

Comparative sequence analysis is the first step to study sequence-structure-function relationship in protein and nucleotide sequences. Some examples of such programs are:
Protein sequences: Blastp, PSI-BLASTand PHI-BLAST
Nucleotide sequences: MEGABLAST, Discontigous-megablast, Blastn.
