Dear vikas

this is the method of formation of picric acid( 2,4,6-trinitrobenzene)

first when it reacts with cons sulphuric acid mixure of o-phinol sulphonic acid and p-phenol sulphonic acid forms 

and when this mix reacts with cons nitric acid  then picric acid form.

Isn’t picric acid 2,4,6-trinitrophenol and therefore the options are wrong?
