Which of the following psychological statements is most authentic and scientifically valid regarding the true psychological implications of 'Extinction'—a central concept under Ivan Pavlov's Classical Conditioning Theory defined as the gradual weakening and ultimate complete disappearance of a conditioned response (CR) when a conditioned stimulus (CS) is repeatedly presented without being followed by the unconditioned stimulus (US)—and its application to modifying unwanted behaviors, alleviating fear or anxiety, and fostering adaptive habits in classroom teaching?

According to Ivan Pavlov's Classical Conditioning, Extinction is the process where a conditioned response (such as salivation or CR) gradually decreases and disappears when the conditioned stimulus (like a bell) is repeatedly presented without food (US). In a classroom context, if a student exhibits negative, unwanted, or attention-seeking behavior solely due to the attention (reinforcement) provided by the teacher or peers, and the teacher stops giving that attention (i.e., extinguishes the reinforcement), the unwanted behavior gradually ceases. This is a highly scientific and effective technique for teachers regarding classroom management and behavior modification.
