From the words lettered A to D choose the word or group of words that best completes the sentence.
Adamu is a very good friend on .... I can rely
Answer Details
The correct word to complete the sentence is "whom". "Whom" is the objective form of "who" and is used to refer to the object of a verb or preposition. In this sentence, "whom" refers to the person (Adamu) on whom the speaker can rely, making Adamu the object of the verb "rely".
