Option B (State Assemblies) is correct because the textbook context clearly states that 'The state elections were held with the Lok Sabha elections.' Additionally, it mentions that voters had to elect 'about 3,200 MLAs and 489 Members of Lok Sabha.' MLAs (Members of Legislative Assembly) are elected to State Assemblies. The Congress party won majority of seats in state assemblies across the country, forming governments in all states. Options A, C, and D are incorrect because the President is not elected through general elections, Rajya Sabha members are elected indirectly, and the Prime Minister is not directly elected but is the leader of the majority party in Lok Sabha.
