The correct answer is D. Glass: water
Step-by-step explanation:
The words presented "Bowl/cereal" relate because one acts as a container of the other one as a bowl can contain cereal. This implies, the pair of words that have the same relationship to the first pair should also show a container relation which would complete an analogy and therefore, the correct answer is "Glass: water" because similar to bowl a glass is an object that acts as a container of other and in this case the element that is contained by the glass is water.
