That would be the imperative mood.
<span>The students read the instructions, discussed how complicated they seemed, and decided to ignore them.
Each verb is a direct-action verb (subject-verb-object) and is in the simple preterite tense. The verbs read, discussed, and decided all follow this structure, unlike "were reading" or "it was decided" .</span>

Your question is incomplete because you have not provided the underlined phrases, which are:
The biggest industry <u>of the Cook Islands</u> is tourism, which brings in more revenue than exporting fish and fruit.
The Cook Islands is a group <u>of 15 small volcanic islands</u>.
The Cook Islands stretch <u>over 800 miles</u>.
An airport <u>on Rarotonga</u> is a destination for tourists to the Cook Islands.
Answer:
The Cook Islands stretch <u>over 800 miles</u>.
Explanation:
Prepositional phrases begin with a preposition and have an object and, sometimes, modifiers. They can also act as adjectives when they modify nouns, and as adverbs when they modify verbs, by demonstrating how, when, where and why the action occurs. In this case, the underlined prepositional phrase functions as an adverbial phrase because it shows where or to what extent the Cook Islands stretch.
The rest of the options are incorrect because they modify nouns, so their object is related to the nouns they modify.
