If a company keeps terms in its mobile app so complex that customers cannot understand them, which risk does this show?

Correct answer: Unfair and non-transparent service terms

The governing concept is transparency and fairness in the legal relationship between a business and its consumers. Contract or app terms should be presented in language and a format that an ordinary customer can reasonably understand, especially when they affect payment, renewal, cancellation, liability, privacy, or complaint rights. Deliberately or negligently using confusing language can prevent meaningful consent and may hide burdensome conditions. It can therefore create a risk of unfair contracting, consumer complaints, regulatory action, invalid or unenforceable provisions, and reputational harm. Option D is correct because it identifies the legal risk created by unintelligible terms. Weather information, office rent, and machine colour do not concern the clarity, fairness, or transparency of consumer service conditions.
