The correct answer is A . Project oversight can be carried out through ad hoc escalations and interventions, among other mechanisms. Oversight is the governance-level observation, review, and direction applied to ensure that the project remains aligned with objectives, risks are understood, decisions are escalated appropriately, and corrective action is taken when necessary. It can include formal reviews, stage gates, assurance reviews, reporting, audits, steering committee decisions, exception handling, escalations, and targeted interventions. Ad hoc escalation is appropriate when an issue, risk, decision, or exception arises outside routine reporting cycles and requires higher-level attention. Option B is not the best answer because oversight does not mean mechanically ensuring that the plan is followed in detail under all circumstances. Projects may require controlled change, replanning, or adaptation. Option C is incorrect because appointing more than one project manager does not inherently provide oversight and may create confusion if responsibilities are not clear. Oversight should be performed through defined governance mechanisms, not by duplicating the project manager role. The uploaded source question identifies ad hoc escalations and interventions as a valid oversight method.
