Q. ________ is/are used by human beings most of the time to control the behaviour of others as well as of themselves.

Correct Answer: (A) Words

Explanation:

Human beings primarily use words to communicate, influence, and control the behavior of others as well as themselves. Language is a powerful tool that allows individuals to express thoughts, emotions, instructions, and intentions. Through verbal communication, people can persuade, instruct, negotiate, and resolve conflicts effectively.

While other options like punishment, rewards, and postures can also influence behavior, they are secondary methods and are not as universally or frequently used as words. Words are the most direct and versatile means of communication and control in human interactions.
