Topic: Fill in the Blank,

Best Answer Explained in Below-:

The sentence states that the island soil has been barren for many years, which implies that the local agricultural conditions are unsuitable for growing crops. When soil is barren, it lacks the nutrients and conditions necessary to cultivate plants effectively. As a result, the islanders would not be able to grow their own food on the island.

In this context, the correct word to fill in the blank is "import" (option B), as it accurately reflects the need for the islanders to obtain food from outside sources. Importing food means bringing it in from other regions or countries where it can be produced. The other options do not fit the context: "deliver" (A) suggests a distribution mechanism rather than sourcing food, "produce" (C) implies growing food locally, which is not feasible due to the barren soil, and "utilize" (D) indicates using something rather than obtaining it. Thus, the only viable choice, considering the islanders’ inability to cultivate their own food, is to import it from elsewhere.
