Afather takes his baby out for a walk. the baby reaches over to touch a pink flower and is stung by a bumblebee sitting on the petals. the next day, the baby's mother brings home some pink flowers. the mother removes a flower from the arrangement and takes it over for her baby to smell. the baby cries loudly as soon as she sees it. according to the principles of classical conditioning, the conditioned stimulus in this scenario is the

The pink flower

Explanation:

Classical conditioning is a type of learning that had a major influence on behavioral psychology, a systematic approach to psychology that emerged in the nineteenth century and assumes that many behaviors are the product of association, reflexes produced by a conditioned response to certain stimuli. This association, moreover, is a consequence of this person's story.

With this, we can conclude that, according to classical conditioning, the conditioned stimulus (which is the one that causes a reaction) is the pink flower that the baby's mother points to him. This is because the baby was stung by a bee when it touched a pink flower, so he associated the flower with the pain he felt at the time of the sting.
