D is an architect receiving Disability Income benefits who is not able to return to work full time, but can work on a part-time basis. Which of these features would allow D to continue receiving benefits?

The correct choice is the Residual Benefit clause because it is specifically designed to support individuals who are partially disabled and can work on a limited basis while still needing financial assistance. This clause allows beneficiaries to receive a portion of their disability benefits even when they return to work part-time. The idea is to provide a smooth transition for individuals who are recovering and may not be able to resume full-time work immediately.

The Elimination Period refers to the time frame (often measured in days) before benefits commence after a claim is filed. This does not directly address the issue of continuing benefits while working part-time.

The Grace Period is a specific time after a premium is due during which the policy remains in force even if the payment has not been made. It does not have any relation to the benefits one can receive while partially disabled.

The Rehabilitation Benefit typically covers costs associated with a rehabilitation program or retraining but does not directly provide ongoing disability income payments for someone who may be able to engage in partial work. Therefore, while it may assist in recovery, it does not directly allow for the continuation of the regular disability income benefits while working part-time.
