Which term describes physical or psychological tension and strain?

The term that describes physical or psychological tension and strain is stress. Stress refers to the body's reaction to challenges or demands that can result in various emotional and physical symptoms. It encompasses feelings of pressure, anxiety, and overwhelm that may arise from life changes, work commitments, or interpersonal relationships.

In contrast to the other options, responsibility pertains to the obligation to perform tasks or duties and does not inherently involve tension or strain. Tolerance refers to the ability to accept or endure various experiences or behaviors without emotional upheaval. Substance abuse implies a pattern of harmful use of substances that leads to addiction and does not specifically refer to the general concept of tension or strain in the same way that stress does. Thus, stress accurately captures the essence of the physical and psychological reactions individuals may experience when faced with challenging situations.
