Which of the following terms indicates a mandatory action?

The term "You Shall" is associated with a mandatory action because it establishes a clear requirement or obligation that must be followed without exception. In various regulatory and legal contexts, "shall" indicates that compliance is not optional; it signifies that the action must be taken and is enforceable. Therefore, when instructions or guidelines use "shall," it conveys a sense of duty and a clear directive that must be adhered to. This contrasts with other terms such as "should," "may," and "could," which imply recommendations, possibilities, or optional actions rather than obligatory ones. Understanding these distinctions is vital in contexts like maintenance practices, regulatory compliance, or operational procedures, where clarity in actions can impact safety, efficiency, and legal accountability.
