A social science excursion trip in a school involved a visit to Ziro, Bombdila, Namdapha National Park, Tawang and Leisang village. On which medium could you ask the students to mark the two states they had visited?

Ziro, Bombdila, Namdapha National Park, and Tawang are all places in Arunachal Pradesh. Leisang is a village in Manipur (famously the last village to get electricity under Saubhagya). Therefore, the two states visited are Arunachal Pradesh and Manipur. Since states are geographical entities, they should be marked on a map, not on a timeline. Hence, option (3) is correct.
