(C) Let us analyze each reaction:$1$. Styrene $(C_6H_5CH=CH_2)$ reacts with $Br_2/CCl_4$ via electrophilic addition to the double bond,but the provided image shows substitution on the ring,which is incorrect for these conditions. However,in the context of typical multiple-choice questions,let us re-evaluate the options.$2$. Aniline reacts with $Br_2/CS_2$ (a non-polar solvent) to give mono-bromination (ortho or para),not tri-bromination. Tri-bromination occurs in water.$3$. Phenol reacts with concentrated $HNO_3/H_2SO_4$ to form $2,4,6$-trinitrophenol (picric acid). This is a correct reaction.Given the options,if the question asks for the correct reaction,only the nitration of phenol is standardly correct as depicted. However,if the question implies identifying the correct chemical transformation,option $C$ is the most accurate representation of the reaction shown.
