Flood insurance is the best answer because traditional personal-lines property policies have commonly restricted or excluded flood-type water exposures, while commercial property policies more often offer flood coverage by endorsement, extension, or separate arrangement for an additional premium. This question is testing the classic distinction between standard personal-lines availability and commercial risk customization. Identity theft coverage is commonly available in personal lines as an endorsement or package extension. Specialized motor vehicle endorsements may also be available depending on the personal automobile or property context. Renovation and remodelling endorsements can be used in personal-lines situations when a dwelling is under construction or materially altered, subject to underwriting approval. Flood, however, has historically been treated more restrictively in personal property insurance because flood losses can be catastrophic, geographically concentrated, and difficult to price without specialized underwriting. For commercial risks, insurers may evaluate the premises, flood zone, construction, elevation, protection, and risk controls and then charge additional premium.
