Which condition states that coverage against fraud depends on truthful representation of facts?

The condition that coverage against fraud hinges on truthful representation of facts is indeed the concept of "Concealment, Misrepresentation, or Fraud." This principle holds that for an insurance policy to be valid, the policyholder must provide an accurate and honest account of relevant information during the application process. If an insured party conceals important facts or misrepresents the truth, it could lead to a denial of coverage when a claim is made. This condition is fundamental in insurance agreements as it promotes transparency and trust between the insurer and the insured.

The other options do not directly deal with the integrity of information provided by the policyholder. "Legal Action Against Us" relates to the procedures to be followed if a claim is disputed. "Control of Property" is concerned with the insured's obligation regarding the property covered under the policy. Lastly, "Policy Period" refers to the duration for which the insurance coverage is in effect. Each of these aspects is important, but they do not address the issue of truthful representation concerning fraud in the way that the concept of "Concealment, Misrepresentation, or Fraud" does.
