When a vendor at a market urges a passerby to buy their vegetables by expressing their financial need, what type of appeal is being utilized?

The correct answer is the appeal to pity. This type of appeal occurs when a vendor or speaker tries to persuade others by invoking their sympathy or compassion. In the scenario described, the vendor expresses their financial need, which is designed to elicit feelings of sympathy from the passerby. This approach aims to create an emotional reaction that might motivate the passerby to make a purchase out of concern for the vendor's situation.

In persuasive communication, evoking pity can be a powerful strategy, as people are often more inclined to help when they feel upset or saddened by someone else's plight. The aim is to create an emotional connection that influences the decision-making process of the listener, encouraging them to act (in this case, by buying the vegetables) out of goodwill or pity for the seller's circumstances.
