Explanation:

• Statement 1st is incorrect: It does not provide right to reject to the voters.

• Statement 2nd is incorrect: NOTA option is not permitted in the Rajya Sabha polls.

• Statement 3rd is incorrect: The candidate with the maximum votes wins the election irrespective of the number of NOTA votes polled.

NOTA stands for "None of the Above." It is an option provided to voters in elections to indicate that they do not support any of the candidates listed on the ballot.

• NOTA was introduced in India in 2013 following a Supreme Court directive to give voters the option of rejecting all candidates contesting in an election.

• It is important to note that NOTA does not provide a right to reject to the voters in the sense of forcing a re-election or cancellation of the election.

• When a voter chooses the NOTA option, it indicates a negative vote, essentially expressing dissatisfaction with the candidates without actively supporting any particular one.

• The introduction of NOTA was aimed at giving voters a means to express their dissatisfaction with the available candidates, thereby encouraging political parties to field better candidates.

• However, NOTA votes are not counted for determining the winner of an election. Even if NOTA receives the highest number of votes, the candidate with the highest number of votes among the contesting candidates is declared the winner.

• NOTA option is meant only for universal adult suffrage and direct elections and not polls held by the system of proportional representation by means of the single transferable vote as done in the Rajya Sabha.

Hence option 4th is correct.
