If the number of seats allocated to a state in the Lok Sabha is 42, then the number of seats reserved for the Scheduled Castes in that state will be

1. Reservation of seats for Scheduled Castes (SCs) in the Lok Sabha is governed by Article 330 of the Constitution. 2. The number of seats reserved for SCs in any state is determined based on the proportion of the Scheduled Castes population in that state to the total population of the state. 3. It is not a fixed fraction (like 1/2, 1/3, or 1/6) of the total number of seats allocated to the state. 4. For a state allocated 42 seats (likely referring to West Bengal or Andhra Pradesh at the time), the number of reserved seats would depend on the SC population percentage in that specific state according to the census used for delimitation. 5. Historically and typically, the number of SC reserved seats in states with around 40-42 total seats has been in the range of 6 to 8. For West Bengal (42 seats), the number of SC reserved seats was 8 post the 2008 delimitation, and likely a similar proportion before. For Andhra Pradesh (pre-bifurcation, 42 seats), it was 6 or 7 depending on delimitation period. Given the options, 6 is the most plausible number representing a realistic proportion (6/42 ≈ 14.3%).
