Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Prussian blue is a dark blue pigment produced by oxidation of ferrous ferrocyanide salts.
In analytical chemistry, it is formed in the prussian blue. assay for total phenols samples and phenolic standards are given acidic $f e r r i c$ $c h l o r i d e$ and $f e r r i y a n i d e$ , which is reduced to $f e r r o c y a n i c l e$ react to form $p r u s s i a n$ $b l u e$ .
