Starfish, with anywhere from five to eight arms, have a strong regenerative ability, and if one arm is lost it quickly replaces it, sometimes by the animal overcompensating and growing an extra one or two.
1. one arm is lost it quickly replaces it, sometimes by the animal overcompensating and
2. one arm is lost it is quickly replaced, with the animal sometimes overcompensating and
3. they lose one arm they quickly replace it, sometimes by the animal overcompensating,
4. they lose one arm they are quickly replaced, with the animal sometimes overcompensating,
5. they lose one arm it is quickly replaced, sometimes with the animal overcompensating

Here, in the correct option if we remove the part “and if one arm is lost it is quickly replaced” the sentence wouldn’t make sense right?
Since this would be left “Starfish, with anywhere from five to eight arms, have a strong regenerative ability sometimes by the animal overcompensating and growing an extra one or two.
Additionally, isn’t the animal overcompensating “by “growing an extra one or two and not as a separate action?

A one arm is lost it quickly replaces it, sometimes by the animal overcompensating and--- it seems as if the plural starfish is pronounced by the first, singular it; in addition in an active voice sentence, the use of by is improper

B one arm is lost it is quickly replaced, with the animal sometimes overcompensating and ------- seems ok with the SV problem avoided altogether. Here the it should logically refer to the arm. correct choice

C they lose one arm they quickly replace it, sometimes by the animal overcompensating, -----use of by is improper in an active voice setting. It should be with the animal rather than by the animal; overcompensating, growing is improper co-ordination. There should be an and in between

D they lose one arm they are quickly replaced, with the animal sometimes overcompensating,’---use of they means that the starfish themselves are replaced; over compensating should be followed by and

E they lose one arm it is quickly replaced, sometimes with the animal overcompensating, --- in a passive voice we need to use by rather than with ; in addition overcompensating should be followed by and
