Correct answer: B. Bow
Explanation: The direct answer is B: the bow. In the Sangam age, the Cheras were one of the important Tamil ruling powers of southern India. Traditional emblems help historians and students distinguish the major dynasties. The Chera emblem is generally remembered as the bow. The Cholas are associated with the tiger, and the Pandyas with the fish. Thus B is correct. Option A, fish, is wrong because fish is traditionally linked with the Pandya rulers. Option C, tiger, is wrong because the tiger is associated with the Cholas. Option D, lion, is wrong because it is not the standard traditional emblem used to identify the Cheras in this comparison. The answer is based on a dynastic symbol, not on the name of a city, a religious sign, or a modern national emblem. A weak student can solve it by learning the three-part set together: Chera–bow, Chola–tiger, Pandya–fish. Do not confuse the order of the dynasties. Memory trick: “Chera carries a bow”; then remember Chola–tiger and Pandya–fish as the remaining pairings.
