Answer: D. By having two characters communicate with each other.
Hope it helps! :-)
The story "Talk" by Harold Courlander and George Herzog has a HUMOROUS tone. The talking characters make the story really humorous, for example the talking yam frightened the farmer when he wanted to dig it. Same with the fish trap, the stool in the chief's house, and so on.
The point of view in this excerpt is definitely third person, because nouns such as Dorothy, and pronouns such as she are used throughout to indicate third person.
However, if you also need to decide whether it is limited or omniscient, I'd choose limited - because we can only see what she is doing, and not what she is thinking and feeling.
