(D) The conversion of phenol to picric acid ($2,4,6$-trinitrophenol) is an electrophilic aromatic substitution reaction. Phenol reacts with concentrated nitric acid $(HNO_3)$ in the presence of concentrated sulphuric acid $(H_2SO_4)$ to undergo nitration at the $ortho$ and $para$ positions,resulting in the formation of $2,4,6$-trinitrophenol,commonly known as picric acid.
