Dr. APJ Abdul Kalam, known as the Missile Man of India, was instrumental in the creation of which of…

The correct choice is: “Principal Scientific Advisor to the Government of India”

The office of the Principal Scientific Adviser (PSA) to the Government of India was created in November 1999, and Dr A.P.J. Abdul Kalam was its first holder, with the rank of a Cabinet Minister, serving until 2001, shortly before he became President of India (2002–2007).

The other offices existed long before him, so he could not have been their first holder. ISRO was set up in 1969 under Vikram Sarabhai; Kalam worked there as project director of the SLV-3 rocket but was not its head, so “Director of the Indian Space Research Organisation” is wrong. DRDO was set up in 1958; Kalam headed it only from 1992 to 1999, so “Director of the Defence Research and Development Organisation” is wrong. The Department of Atomic Energy dates from 1954 and its first Secretary was Homi J. Bhabha, so “Secretary to the Department of Atomic Energy” is wrong.
