$\mathrm{D}$ is the nitronium ion, ${\mathrm{NO}}_2^{+}$, the conventional electrophile in aromatic nitration. Its standard $\mathrm{O}=\mathrm{N}=\mathrm{O}$ Lewis structure gives nitrogen a complete octet; it is electrophilic because its positive charge and accepting orbitals allow attack by the arene pi system. A is a methyl cation, $\mathrm{B}$ is nitrosonium (associated with nitrosation), and $\mathrm{C}$ is a methyl radical. None of these is the conventional nitrating species.
