The correct answer is Thiruvananthapuram, the capital of Kerala. Thiruvananthapuram serves as the administrative and legislative headquarters of Kerala, housing the state secretariat, the Legislative Assembly, and the offices of the Governor and Chief Minister. Notably, Thiruvananthapuram, also called Trivandrum, is known for the Padmanabhaswamy Temple, one of the richest temples in the world, and Kerala has the highest literacy rate among Indian states. The other options given in this Kerala question are capitals of different Indian states, and candidates often confuse them because Static GK questions on state capitals are frequently tested together in a single set. Dispur is the capital of Assam, not Kerala. Imphal is the capital of Manipur, not Kerala. Aizawl is the capital of Mizoram, not Kerala. None of these cities administers Kerala; only Thiruvananthapuram holds that constitutional status. Competitive exams such as SSC CGL, SSC CHSL, State PSC, and Railway exams often feature a Kerala question like this one on Thiruvananthapuram, which shows why questions on Indian state capitals are considered high-scoring, since they test direct factual recall rather than complex reasoning. Remember Thiruvananthapuram as the capital of Kerala, and clearly distinguish it from the distractor capitals used here — Dispur, Imphal, Aizawl — to avoid marking the wrong answer under exam-time pressure.
