OG SC- 114

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.

A one arm is lost it quickly replaces it, sometimes by the animal overcompensating and
B one arm is lost it is quickly replaced, with the animal sometimes overcompensating and
C they lose one arm they quickly replace it, sometimes by the animal overcompensating,
D they lose one arm they are quickly replaced, with the animal sometimes overcompensating,
E they lose one arm it is quickly replaced, sometimes with the animal overcompensating,

D they lose one arm they are quickly replaced, with the animal sometimes overcompensating,

In A, the first it (singular) does not agree with its intended antecedent, starfish (plural). Eliminate A.

In D, the second they (plural) does not agree with its intended antecedent, arm (singular). Eliminate D.

In C and E, sometimes by the animal and sometimes with the animal imply a nonsensical meaning: that the lost arm is replaced sometimes NOT BY the animal or sometimes WITHOUT the animal.
Eliminate C and E.

The correct answer is B.

Where a modifier is placed affects MEANING.
Always notice when a modifier such as SOMETIMES changes position in the answer choices.
In the OA, sometimes correctly modifies overcompensating and growing:
If one arm is lost it is quickly replaced, with the animal SOMETIMES OVERCOMPENSATING AND GROWING an extra one or two.

I eliminated C, and E in the following ways.
C-sometimes by the animal overcompensating,growing an extra one or two.- Here we need 'and' between overcompensating and growing.

Besides, Starfish can't replace arm by their own. Actually arm is replaced naturally. So, it is wrong to say " they replace it"

E-sometimes by the animal overcompensating growing ----. Overcompensating growing- wrong

Am I correct in my elimination process?
