Explanation:

In contract law, when a ticket references conditions (e.g., “for conditions see back”), the passenger is generally bound by those conditions, whether they read them or not, provided the reference is clear and the conditions are reasonably accessible. This principle ensures that contractual terms are enforceable when properly incorporated. Option A is correct. Option B is incorrect, as ignorance of terms does not exempt the passenger. Option C is vague and not a legal standard. Option D is incorrect, as option A applies. The answer “A” is as provided in the attachment.
