When communication fails to shift an opponent’s attitude, escalation to a higher authority like the project sponsor is a strategic move in SAP OCM. Option C is correct because the sponsor’s involvement leverages their influence to address resistance, aligning with SAP’s emphasis on leadership support in stakeholder management. Option A is incorrect—financial incentives are not a standard OCM practice and may undermine genuine buy-in. Option B is impractical; steering committee meetings are for decision-making, not resolving individual resistance. Option D could help but is less effective than sponsor engagement, as enablement alone may not address deeper concerns.
