Option 1 states that the Presiding Officer of the Rajya Sabha is elected every year. This statement is incorrect because the term of the Presiding Officer of the Rajya Sabha is not for a year, but for a longer period.
Option 2 suggests that the Presiding Officer of the Rajya Sabha is elected for a term of 5 years. This statement is incorrect because the Presiding Officer of the Rajya Sabha is not elected for a term of 5 years.
Option 3 claims that the Presiding Officer of the Rajya Sabha is elected for a term of 6 years. This statement is incorrect because the Presiding Officer of the Rajya Sabha is not elected for a term of 6 years.
Option 4 is the correct answer. It states that the Vice President of India is the ex officio Presiding Officer of the Rajya Sabha. This means that the Vice President, by virtue of being the Vice President, automatically holds the position of the Presiding Officer of the Rajya Sabha. The Vice President`s role is to preside over the sessions of the Rajya Sabha and ensure that the proceedings are conducted in an orderly manner.
