In Texas, the seller's disclosure notice must be provided:

Option A is incorrect because the Texas Seller's Disclosure Notice must be provided before the buyer signs the contract, not at closing. Providing it at closing would violate Texas law and could result in the buyer having the right to terminate the contract or sue for damages. The disclosure is required to give the buyer full information before committing to purchase the property.

Option C is incorrect because while 5 days is a common timeframe in other states for providing disclosures after contract execution, Texas requires the disclosure to be provided before the contract is signed, not within 5 days after.

Option D is incorrect because seller's disclosures in Texas are not optional or contingent on buyer request. They are a mandatory requirement that must be provided before contract execution regardless of whether the buyer specifically asks for them.
