Which of the following pairs correctly matches appetite and hunger?

• A. Appetite: physiological drive to eat; Hunger: psychological desire to eat
• B. Appetite: psychological desire to eat; Hunger: physiological drive to eat
• C. Appetite: taste preference; Hunger: appetite
• D. Appetite: energy deficit; Hunger: mood

Answer: (B)

The question tests the difference between appetite and hunger. Appetite is the psychological desire to eat, shaped by mood, cues, culture, and external influences. Hunger is the body's physiological drive to eat, signaling energy needs and driven by signals like stomach contractions and hormones such as ghrelin acting on the brain.

Thus, the best pairing is appetite as the psychological desire to eat and hunger as the physiological drive to eat. You can experience hunger with physical cues like a growling stomach or low energy, while appetite might rise—in tandem or independently—due to cravings, environment, or emotions, even without true hunger.

The other descriptions mix these concepts, such as defining appetite as taste preference or equating hunger with mood or energy deficit alone, which doesn't capture the distinct psychological vs. physiological nature of appetite and hunger.
