Single Transferable Vote system

The correct answer is Option 1 - Single Transferable Vote system

Single Transferable Vote system (STV), is followed for Rajya Sabha elections.

A third variant of PR, the Single Transferable Vote system (STV), is followed for Rajya Sabha elections. Every State has a specific quota of seats in the Rajya Sabha. The members are elected by the respective State legislative assemblies. The voters are the MLAs in that State. Every voter is required to rank candidates according to her or his preference. To be declared the winner, a candidate must secure a minimum quota of votes, which is determined by a formula:

$\left(\frac{\text{Total votes polled}}{\text{Total number of candidates to be elected + 1}}\right) + 1$
