As of May 2008, who was the Managing Director of the Delhi Metro Rail Corporation?

The correct choice is: “Shri E. Sreedharan”

E. Sreedharan, often called India’s “Metro Man”, was the Managing Director of the Delhi Metro Rail Corporation (DMRC) from 1995 until he retired at the end of 2011. He had earlier built the Konkan Railway. Under him the first phases of the Delhi Metro were completed ahead of schedule. (He was succeeded by Mangu Singh in January 2012.)

“B.L. Joshi, Lt. Governor of Delhi” held the office of Lt. Governor (2004–07), not the post of DMRC Managing Director; “Sam Pitroda” was chairman of the National Knowledge Commission; and the “Chairman of the Indian Railway Board” heads the Railway Board, not DMRC.
