The NOTA (None of the Above) symbol in India was designed by the National Institute of Design (NID) in Ahmedabad.
The symbol was introduced in 2013 following a Supreme Court directive that gave voters the right to reject all candidates in elections.
The NOTA symbol features a ballot paper with a black cross on it, signifying rejection of all candidates.
The National Institute of Design, Ahmedabad is known for its contributions to design in India and has created several important symbols and designs for national use.
The other institutions mentioned in the options - the National School of Design, Bengaluru (which is not a well-known institution), the Indian Institute of Technology, Bombay (which focuses more on engineering and technology), and the Election Commission of India (which implements election symbols but does not design them) - were not responsible for creating the NOTA symbol.
