Which of the following methods do not form ceramic nano particles? Correct Answer Saponification

Sol gel is the most common method of preparation of ceramic nano particles. This method involves the mixture of a gel and a solution containing nano particles to form the ceramic. Sintering is a method involving pressure and heat to form ceramics. Reverse micro emulsions (Water in oil micro emulsion method) are widely used as an ideal method to prepare inorganic nano particles.

The critical reasoning question is based on a short argument, a set of statements, or a plan of action. For each question, select the best answer of the choices given. The size of particles is directly linked to their potential for causing health problems. Small particles less than 10 micrometers in diameter cause the greatest problems, as they can get deep into the lungs and some may get into the bloodstream. One being exposed to such particles can affect both the lungs and the heart of a person. But there are particles that are causing environmental effects too, few of which are given below.  Which among the following below options does not talk about the effects of these particles on the environment?
