Which disclosure must a Texas real estate agent provide to all parties?

Agency relationships form the foundation of real estate transactions, determining how agents represent clients and their responsibilities. This question tests knowledge of Texas-specific disclosure requirements at first contact. The correct answer is A because Texas mandates the Information About Brokerage Services (IABS) form as the initial disclosure to establish agency relationships. Option B (Transfer Disclosure Statement) is specific to property condition disclosures, not agency. Option C (Lead-Based Paint Disclosure) is federally required for pre-1978 housing but not a general disclosure. Option D (Agency Confirmation Statement) comes after establishing agency, not at first contact. This question is straightforward but requires understanding the timing and purpose of different disclosures. Many students confuse mandatory disclosures with optional ones or mix up the timing requirements, failing to recognize that IABS is specifically required at 'first substantive contact' with all parties in Texas transactions.
