Concept:
Mohan Rakesh was a central figure in modern Hindi literature, known for his contribution to the 'Nayi Kahani' movement and for writing plays that explored complex human relationships and existential themes.
Step 1: Verifying the authorship of the listed plays.
• Ashadh Ka Ek Din (A): His first play (1958), based on the life of Kalidas.
• Lehron Ke Rajhans (C): A play exploring the conflict between spiritual and worldly life.
• Aadhe Adhure (D): A landmark play depicting the fragmentation of a middle-class family.
• Pairon Tale Ki Zameen (B): His final, unfinished play, completed by Kamleshwar.
• Tajmahal Ka Tender (E): A satirical play written by Ajay Shukla, not Mohan Rakesh.
Thus, A, B, C, and D are the plays written by Mohan Rakesh.
