Amino Acid Sequences of a Homologous Protein Found in Three

Amino acid sequences of a homologous protein found in three species of dragonflies are presented below:
Dragonfly 1: Met-Gln-Leu-Ile-Val-Arg-Ser
Dragonfly 2: Met-Gln-Leu-Ile-Val-Ser
Dragonfly 3: Met-Gln-Leu-Val-Arg-Ser
How many gaps are required to properly align these three species? (Note: Align Dragonfly 2 and Dragonfly 3 sequences with the Dragonfly 1 sequence.)

A) Zero
B) One
C) Two
D) Three
E) Four
