Participial modifier “Having received…” incorrectly modifies “Spanish wildlife officials”	Modifier

Explanation:

In the sentence, the participial modifier ‘Having received…’ incorrectly modifies ‘Spanish wildlife officials’. Instead, it should logically modify ‘the Galapagos giant tortoise population’ which is directly affected by the actions mentioned in the modifier.

D – Modifier ‘Having received…’ incorrectly modifies ‘the Spanish’. Hence, eliminated.

E – Modifier ‘Having received…’ incorrectly modifies ‘wildlife officials’. Hence, eliminated.
