What happened to the glycerol formed during the saponification reaction?

This is what happen the fatty acid by itself and the glycerol by itself are both water soluble because of the polar oxygen atoms on the ends of these molecules. Saponification is the term applied to the hydrolysis of fats using a strong alkali like lye. Glycerol (aka glycerine) is simply a tri-alcohol, i.e. an alcohol with three OH groups. It has chemistry similar to that of ethanol.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
