Which type of duty can be imposed by statute?

The correct choice refers to the concept of mandatory acts legislated by law, which encapsulates the essence of duties imposed by statutes. Statutory duties arise from specific laws enacted by legislative bodies that require individuals or entities to perform or refrain from certain actions. These duties can include a wide variety of obligations, such as adhering to safety regulations, complying with tax laws, or fulfilling contractual requirements dictated by state or federal statutes.

Unlike legal obligations of professionals, which may be derived from both statutes and professional codes of conduct, or natural responsibilities, which are often moral or ethical in nature, statutory duties are explicitly laid out in legal texts. Voluntary obligations of the community are not imposed by law and usually arise from social norms or individual commitments rather than formal legislative action. Thus, the focus on mandatory acts legislated by law accurately reflects the nature of duties that are enforceable and legally binding.
