Answer: (A)

Verified step by step guidance

1. Step 1: Understand the concept of a primary reinforcer. In classical conditioning, a primary reinforcer is a stimulus that naturally and automatically triggers a response without prior learning because it satisfies a biological need.
2. Step 2: Identify examples of primary reinforcers. These typically include things like food, water, warmth, and other stimuli that are inherently rewarding due to their survival value.
3. Step 3: Compare the options given: Food, Praise, A gold star sticker, and Money. Consider which of these satisfies a biological need directly and naturally.
4. Step 4: Recognize that food is a primary reinforcer because it directly satisfies hunger, a biological need, whereas praise, stickers, and money are secondary reinforcers that acquire their value through association with primary reinforcers.
5. Step 5: Conclude that the best example of a primary reinforcer in the list is food, as it naturally elicits a response without prior learning.
