Explanation:

• General elections follow the secret ballot system whereby choice of the voter is confidential to him/her only. Section 94 of the Representation of People Act provides that Secrecy of voting is not to be infringed.
• As per Article 55(3) of the Constitution of India, the election of the President shall be held in accordance with the system of proportional representation by means of single transferable vote and the voting at such election shall be by secret ballot.
• Open ballot voting applies in election to Council of States. Every political party which has its member(s) as MLAs can appoint an authorized agent to verify as to whom its members have voted. The authorized agent will be seated inside the polling station in seats provided by the R.O. In case of MLAs who are members of political parties, after they mark the vote and before inserting the ballot box, are required to show the marked ballot paper to the authorized agent of their party. Hence only statement 1&2 are correct.
