Choose the correct answer from the options given below:

The correct answer is B, C & E.

Nissim Ezekiel (1924–2004) was a foundational figure in modern Indian English literature, widely acclaimed as a poet, playwright, critic, and editor. While he is most famous for his poetry, he also wrote several notable plays that satirize urban Indian society, relationships, and cultural pretentiousness.

Let's analyze the options provided to identify the plays written by Nissim Ezekiel:
1. Marriage-Poem (B): This is a one-act play written by Nissim Ezekiel. It deals with the themes of marital discord, the disillusionment of married life, and the complexities of male-female relationships in an urban middle-class setting.
2. Nalini (C): Subtitled "A Comedy in Three Acts," this is one of Ezekiel's most well-known plays. It is a satire on the art world, advertising, and the intellectual pretension of the modern Indian elite.
3. Sleepwalkers (E): This is a one-act farce written by Ezekiel. It satirizes the cultural servility of Indian intellectuals towards American visitors and their search for patrons, exposing their lack of genuine identity.
All three of these plays—Marriage-Poem, Nalini, and Sleepwalkers—were published together in his collection titled Three Plays (1969).

Looking at the other options:
- Savaksa (A): This is not a play by Nissim Ezekiel.
- Mister Behram (D): This play was written by Gieve Patel, another prominent Indian poet and playwright, not by Nissim Ezekiel.

Therefore, the three plays written by Nissim Ezekiel are B, C, and E.
