The correct answer is option 2, which states that statement 2 is correct while statement 1 is incorrect.

Statement 1 is incorrect because the National Knowledge Commission is not an advisory body to the Prime Minister constituted as per the provisions of the Constitution of India. Instead, it was an advisory body to the Prime Minister of India that was established by the Indian government in 2005. Its purpose was to provide recommendations and reform measures for improving the quality of education and knowledge dissemination in the country.

Statement 2 is correct as Mr. Sam Pitroda was indeed the Chairman of the National Knowledge Commission. He was appointed to this position by the Indian government and served as the Chairman from 2005 to 2009.

Therefore, option 2 is the correct answer as it correctly identifies that statement 2 is true while statement 1 is false.
