Answer 1

Option 4) A woman injects heroin into her veins to obtain a "rush." This example clearly illustrates the concept of craving, where an intense desire or urge drives an individual to engage in harmful behaviors.

Step-by-step explanation:

The best example that illustrates the concept of craving is option 4) A woman injects heroin into her veins to obtain a "rush." Craving refers to an intense desire or urge to consume or engage in a certain behavior, typically associated with addiction or intense pleasure. In this example, the woman craves the rush and euphoria that heroin provides, which drives her to inject the drug into her veins.

This example is a clear illustration of how craving can override rational thinking and lead individuals to engage in harmful behaviors to satisfy their cravings.
