According to question ,
Let us assume Number of Kannada = K , Number of Tamil = T and Number of Telugu = Te
Here , n(K) = 11; n(T) = 20; n(Te) = 11
n(K ∩ T ∩ Te) = 1
n(K ∩ T) = n(T ∩ Te) = n(Te ∩ K) = 2
n(K U T U Te) = n(T) + n(K) + n(Te)  n(K ∩ T)  n(T ∩ Te)  n(Te ∩ K) + n(K ∩ T ∩ Te)Correct Option: C
