When phenol is reacted with ${\mathrm{CHCl}}_3$ and NaOH  followed by acidification, salicylaldehyde is obtained. Which of the following species are involved  in the above mentioned reaction as intermediates?

${\mathrm{CHCl}}_3+\mathrm{NaOH}\to \mathrm{NaCl}+{\mathrm{H}}_2\mathrm{O}+{\mathrm{CCl}}_2$

Salicyaldehyde is produced when phenol combines with ${\mathrm{CHCl}}_3$ in NaOH in the Reimer-Tiemann reaction. The reaction's mechanism is described above. The intermediates in this case are options D.
