Step 1: Task.
Pick the play that Peter Brook, the English theatre director, staged.
Step 2: Key idea.
Peter Brook is known for his book 'The Empty Space' and for his international theatre company in Paris. His biggest Indian-themed work was the Mahabharata, a stage epic of about nine hours that toured the world from 1985 and was made into a TV film and a movie.
Step 3: Compare the choices.
Ramayana: no Brook production exists, so it is out.
Mahabharat: this is Brook's famous epic, so it is in.
Mrichkatikam: a classical Sanskrit drama of Shudraka that Brook never directed, so it is out.
Urubhangam: a one act play of Bhasa on Duryodhana, not part of Brook's work, so it is out.
Step 4: Result.
Only the Mahabharat fits the question.
Always read the options slowly and match each name with a clear fact you know about it. Names that sound close can belong to very different traditions, so do not guess from the sound of a name alone. Writing the key fact next to each name, as done above, makes the elimination quick and safe. This habit also helps in similar questions on theatre personalities, plays and groups.
Final Answer:
The play is Mahabharat, so the answer is option 2.
