Coverage D can be purchased and applies if property under Coverage A, B, or C becomes damaged or destroyed by a peril covered in the policy for the loss of rental income. Coverage E can be purchased and it pays for the increase in normal living expenses the insured incurs while the described premises are unfit for normal use. Like Coverage D, this is an indirect loss of use coverage, so it applies only when a direct damage claim to A, B, or C is covered by the policy.
