In the question below choose the word(s) or phrase(s) which best fill(s) the gap: Ladies and gentlemen, our guest speaker, Dr. Oni _____ also a resident doc...

Answer Details

The best option to fill the gap is "is." The sentence is in the present tense and refers to Dr. Oni's current occupation as a resident doctor at the teaching hospital. The phrase "also a resident doctor at the teaching hospital" is a clue that we are talking about Dr. Oni's current occupation. Therefore, the correct verb form to use is the present tense "is." Option a, "who is," correctly uses the present tense verb "is" to match the tense of the sentence. Option b, "which is," is incorrect because "which" is used to refer to things or objects, not people. Option c, "who was," is incorrect because it uses the past tense verb "was" which does not match the present tense of the sentence. Therefore, option d, "is," is the correct answer to fill the gap in the sentence.
