Select the most appropriate option to fill in blank number 1.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. are.
Context: The sentence talks about dolphins in the present general truth, so the verb should be in the simple present tense and plural in form to agree with the plural subject 'dolphins.'
Meaning of the words:
Has: Third-person singular form of “have”; used with singular subjects.
Was: Past tense of “is”; inappropriate as the sentence is in present tense.
Are: Plural form of “be”; used with plural subjects.
Is: Singular form of “be”; used with singular subjects.
Correct word: Are
Reason: “Dolphins” is a plural noun and needs a plural helping verb “are” for correct subject-verb agreement in the present tense.
Final Sentence: Dolphins are regarded as the friendliest creatures in the sea.
Hence the chosen option is correct.
