Which of the following could potentially expose a products supplier to liability?

Providing inadequate warnings is a key factor that can expose a product's supplier to liability under the theory of products liability. Two main grounds for liability arise in this context: failure to warn consumers of potential dangers associated with the use of a product and failure to provide adequate instructions for safe use. Manufacturers and suppliers have a duty to inform consumers about any risks that may not be obvious, and if they fail to do so, they can be held liable for injuries that occur as a result.

In many jurisdictions, a product supplier’s obligation extends to ensuring that warnings are clear, prominent, and understandable. If the warnings are ambiguous or not sufficiently conspicuous, and a consumer is harmed by the product, the supplier can be found liable for that negligence.

Other options do not create potential liability in the same way. A lack of advertising doesn't inherently mean a product is unsafe or that a supplier is liable; it simply indicates a marketing strategy. Making required disclosures is in line with regulatory compliance, suggesting the product is being marketed responsibly. Having a large market share does not affect liability directly; rather, liability focuses on the actions that could lead to harm, not the scale of business operations.
