The correct answer is (a) 1971.
The Lokpal Bill is a proposed law in India that would create an independent anti-corruption body to investigate and prosecute cases of corruption against public officials. The bill was first introduced in Parliament in 1971, but it has been repeatedly delayed and amended. The latest version of the bill was introduced in Parliament in 2011, but it has not yet been passed.
The Lokpal Bill has been met with mixed reactions. Some people believe that it is an essential tool to fight corruption, while others believe that it is an unnecessary and expensive bureaucracy. The bill is likely to continue to be debated in Parliament for some time to come.
The other options are incorrect because they are not the years in which the Lokpal Bill was first introduced in Parliament.
