Which of the following pairs of the king and his dynasty in early historical Tamilakam is/are not correctly matched? 1. Senguttuvan : Chera 2. Udiyanjeral : Chola 3. Nedunjeliyan : Pandya

In early historical Tamilakam (Sangam Age), Senguttuvan was a famous Chera king celebrated in the Silappadikaram and associated with the Pattini cult — pair 1 is correctly matched. Udiyanjeral was also a Chera king (not Chola), famous for feeding both armies at the Kurukshetra war according to Sangam tradition — so pair 2 is incorrectly matched. Nedunjeliyan was a celebrated Pandya king who won the Battle of Talaiyalanganam — pair 3 is correctly matched. Therefore, only pair 2 is not correctly matched.
