Final answer:
The correct option among the four is 'Amar, Binod, Chand and I were all cited'. In general, we use 'I' rather than 'me' when the pronoun is part of a compound subject.
Step-by-step explanation:
The correct option among the four given is (b) Amar, Binod, Chand and I were all cited. In English language, when a pronoun is part of a compound subject, we commonly use pronouns like I, he, she, and they, rather than me, him, her, and them. For example, 'Peter and I went to the park', not 'Peter and me went to the park'. Also, the same pronoun form applies when the compound subject is being compared to another term or another pronoun. This is the case of our sentence.
