AnswerC
ExplanationA customary benefit refers to benefits that are traditionally offered by employers, though not legally required. Retirement plans, such as 401(k) plans or pension plans, are common examples of customary benefits. These plans provide financial security for employees in their post-working years and are often used by employers to attract and retain talent by offering long-term financial planning options.
