E Correct answer
Explanation

This option is correct because probably the most well-known progressive alignment program is Clustal. Clustal is a progressive multiple alignment program available either as a stand-alone or on-line program. Poa (Partial order alignments) is a progressive alignment program that does not rely on guide trees. Instead, the multiple alignment is assembled by adding sequences in the order they are given.
