The correct answer is 'Compromised hardware or software' because suppliers have direct access to the components and programs that enterprises use, making it possible for them to introduce compromised products into an organization's infrastructure. 'Data corruption during transmission' focuses on data in transit rather than supply chain vulnerabilities. 'Inadequate customer service' does not directly relate to security issues, and 'Unauthorized data sharing' is a concern with entities that handle data, but it does not specifically relate to the risks posed by suppliers in the supply chain.
