C Correct answer
Explanation

It is incorrect. Linde’s process is a method of liquefying air or other gas by repeated compression and expansion producing cooling by the Joule-Thomson effect. Contact process is a method of producing sulphric acid in high concentrations needed for industrial processes. Deacon’s process is a method of obtaining chlorine gas by passing hydrochloric acid gas over heated slag, which has been previously saturated with a solution of some metallic salt. Ostwald process is a chemical process for making nitric acid (HNO3).
