Solution:Kannada, Malayalam → rightarrow Assamese, Gujarati, Nepali → rightarrow Mizo, Kokborok, Bodo → rightarrow Tamil, Telugu: Backward Control is a syntactic phenomenon where the overt subject appears in the embedded clause, while the matrix clause subject position is empty, and both positions are interpreted as having the same subject. In India, this phenomenon is attested in several Indo-Aryan (Assamese, Gujarati, Nepali), Dravidian (Kannada, Malayalam, Tamil, Telugu) and Tibeto-Burman languages (Mizo, Kokborok, Bodo). These languages allow constructions where the semantic subject appears in the lower clause, while the upper clause subject is unexpressed but controlled by the embedded subject. Khasi and Munda languages (E) show different clause-linking behaviours and do not exhibit classical backward control. Hence, the languages belonging to groups A, B, C and D display backward control.
