The correct answer is (d) 34.
The Bahujan Samaj Party (BSP) won 34 seats in the elections to the U.P. Legislative Council held in January 2010. This was the highest number of seats won by any party in the elections. The BSP’s victory was attributed to its strong performance in the 2007 Uttar Pradesh Legislative Assembly election, in which it won 206 seats. The BSP’s victory in the 2010 Legislative Council elections was seen as a sign of its growing popularity in Uttar Pradesh.
