Explanation:

Fourth option is correct.
The Elected members of the lower house of the State legislature have the right to vote in the elections to both the Lok Sabha and the Rajya Sabha.
Members of the Lok Sabha are elected by the adult universal suffrage which guarantees every Indian citizen his right to directly elect the Member of Parliament (MP) from his constituency by casting a vote.
On the other hand, Rajya Sabha members are indirectly elected by the Members of Legislative Assemblies (MLA) of every Indian state and territorial legislature.
MLA, being a legitimate citizen of India as well as a representative of people from his constituency in his respective state assembly, qualifies to vote in elections to both the Lok Sabha as well as the Rajya Sabha.
