The activity in which the champions of TRACT are not involved is _________________ .
Tiger Reservation and Conservation Trust (TRACT) is a non-governmental organization as mentioned in the passage. The Dhanwateys (the champions of TRACT) are mentioned to have been involved in discovering the secrets of the forest, walking the trail of the tigers, and living in the deciduous forest. Option A, killing the tigers in that area, is completely contradictory to what the Dhanwateys believed in. Hence, option A is the correct answer.
