In a conditional sentence if X, (then) Y, rhetorical flow is enhanced by the two clauses sharing the same structure. If one clause is passive, the other should be passive; if one clause is active, the other should be active, too.
A.The conditional clause has a passive verb, while the result clause has an active verb. The pronoun it should be plural since it refers to starfish. We know that starfish is plural in this sentence because it agrees with have in the main clause .
