Behavior conditioning can be done today through: a Advertising b. Transp ortation c. Propaganda d. School

The correct answer is d. School.<br /><br />Behavior conditioning refers to the process of shaping and reinforcing desired behaviors through various methods, such as rewards, punishments, and positive reinforcement. Schools play a significant role in behavior conditioning by implementing rules, guidelines, and consequences to promote positive behaviors and discourage negative ones among students.<br /><br />While advertising, transportation, and propaganda can influence behavior to some extent, they are not primarily designed for behavior conditioning. Schools, on the other hand, have a structured environment and established systems to condition and reinforce behaviors among students.
