From the words or group of words lettered A to D, choose the word or group of words that best completes the sentence.

It is I who ......... to blame for the lapses.

Answer Details

The correct option is "am". In this sentence, the subject is "I" which is a first-person singular pronoun. Therefore, the correct form of the verb "to be" to use is also the first-person singular "am". So, the sentence should read: "It is I who am to blame for the lapses."
