Assertion (A): The Indian Constitution establishes a separation of powers among the legislature, executive, and judiciary, guaranteeing judicial independence to ensure impartial justice and uphold the rule of law. Hence, the assertion is correct. Reason (R): Judicial independence necessitates an impartial judiciary that does *not* favour the government or any other entity. The judiciary's role is to interpret law and the Constitution objectively, acting as a check on the executive, not assisting in implementation through bias. Consequently, the reason contradicts judicial independence and is incorrect. Because (A) is correct and (R) is incorrect, this aligns with option (3).
