What is the tenure of the Chief Election Commissioner of India?

6 years or up to the age of 65 years, whichever is earlier.

The correct answer is Option 1 - 6 years or up to the age of 65 years, whichever is earlier.

The Chief Election Commissioner (CEC) of India, as well as the Election Commissioners, has a tenure of six years or until the age of 65, whichever comes first. This was established by the 15th Amendment Act of 1989, which introduced this provision to ensure the independence and stability of the Election Commission of India.
