Bufo marinus toads, fierce predators that will eat frogs, lizards, and even small birds, are native to South America but were introduced into Florida during the 1930âs in an attempt to control pests in the stateâs vast sugarcane fields.

A. are native to South America but were introduced into Florida during the 1930âs in an attempt to control
B. are native in South America but were introduced into Florida during the 1930âs as attempts to control
C. are natives of South America but were introduced into Florida during the 1930âs in an attempt at controlling
D. had been native to South America but were introduced to Florida during the 1930âs as an attempt at controlling
E. had been natives of South America but were introduced to Florida during the 1930âs as attempts at controlling

Choice A is best. The phrasing are native to correctly suggests that the toad species in indigenous to, and still exists in, South America.

In B, native in is unidiomatic; in C and E, natives of illogically suggests that each toad now in Florida hails from South America.

In D and E, had been inaccurately implies that the toads are no longer native, or indigenous, to South America, and introduced to Florida is unidiomatic. Both as attempts in B and E and as an attempt in D are wrong because the attempt consists not of the toads themselves, but of their introduction into the environment.

The correct phrase, in an attempt, should be completed by an infinitive (here, to control), as in A.

A. are native to South America but were introduced into Florida during the 1930âs in an attempt to control
B. are native in South America but were introduced into Florida during the 1930âs as attempts to control
C. are natives of South America but were introduced into Florida during the 1930âs in an attempt at controlling
D. had been native to South America but were introduced to Florida during the 1930âs as an attempt at controlling
E. had been natives of South America but were introduced to Florida during the 1930âs as attempts at controlling

Choice A is indeed the answer.
'native to' and 'in an attempt to' are correct usages

Choice A : This choice uses idiomatic expressions 'native to' and 'in an attempt to'. Simple Present tense in 'Toads are native to' is correct to express the fact.
Choice B : 'native in' and 'as attempts to' are incorrect.
Choice C : 'natives of' is accepted when referred to People and not when referred to Animals.
Choice D : Usage of 'had been' is illogical. It suggests that toads are no more native to South America, which is nonsensical.
Choice E : Incorrect for the reasons cited in Choice D and C
