I believe the answer is B. If you look up the definition of the words, you can get your answer by the process of elimination.
Hydrolysis is defined as a chemical process of decomposition that involves the splitting of a bond and addition of the elements of water. The question asks what reaction occurs when you combine a fat and water, and tells you what the two elements are after that particular fat and water are combined, fatty acids and glycerol. If hydrolysis is splitting of a bond, what bond is being split?
Adhesion is the sticking together of two substances. The question clearly states that the combination of the two initial substances result in the creation of two different types of substances, meaning that they are not sticking together. One of those substances, glycerol, is also known as glycerin, which is a sweet, syrupy hygeroscopic alcohol used as a moisturizing agent, emollient and lubricant. Sounds similar to the process of making soap.
Cohesion is the process of sticking together tightly. I don't see that as being the case here, considering the wording of the question. Cohesion can also be considered a synonym of adhesion, depending on the circumstances in which it is being used.
Dehydration is the process involving the removal of water. Synthesis is the composition or combination of parts or elements so as to form a whole, or the production of a substance by the union of chemical elements, groups or simpler compounds, or by the degradation of a complex compound. Fat and water are simple compounds, and according to the question, these two simple compounds are combined and form two entirely new and separate chemicals or elements. The term "dehydration synthesis", simply put, is the removal of water (because water is not one of the elements that are ultimately left over after the combination of fat and water) and the composition, or combination, of parts or elements (in this case, the fat and water), forming two substances.
Does that make sense to you?
