Option 1 -> The passage shows Deven is a lecturer, not a government official.
Option 2 -> The poet directly questions this contradiction: "you tell me it is for an Urdu magazine you wish to interview me. If so, why are you teaching Hindi?" - this is the source of his suspicion.
Option 3 -> No evidence in the passage that Deven criticized Urdu poetry.
Option 4 -> There is no mention of rival publications in the passage.
Hence, Option 2 -> The poet finds it suspicious and contradictory that someone teaching in a Hindi department would want to interview him for an Urdu magazine. He directly confronts Deven with "If so, why are you teaching Hindi?" This contradiction makes the poet accuse Deven of being a "spy" sent "to destroy whatever remains of Urdu, hunt it out and kill it." -> correct
