Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Cyanotype print is made by exposing a negative to a paper prepared by soaking in ammonium citrate of iron and potassium ferricyanide. Reason (R): That is why it looks like a blueprint but is permanent. In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A).
• C. (A) is correct but (R) is not correct.
• D. (A) is not correct but (R) is correct.

Hint:

Remember the important facts about Cyanotype: \[ \boxed{ \begin{aligned} \text{Inventor} &\rightarrow \text{Sir John Herschel (1842)}, \text{Chemicals} &\rightarrow \text{Ferric Ammonium Citrate + Potassium Ferricyanide}, \text{Colour} &\rightarrow \text{Prussian Blue}, \text{Common Name} &\rightarrow \text{Blueprint Process}. \end{aligned} } \] Mnemonic: “Cyanotype = Blue Print with Blue Chemicals.”
