Final answer:
The Loan Estimate (LE) is the disclosure that is required to be provided to the applicant within 3 days of application under Regulation X. Option A
Step-by-step explanation:
The disclosure that is required to be provided to the applicant within 3 days of application under Regulation X is the Loan Estimate (LE).

The other options mentioned: the Closing Disclosure (CD), the Mortgage Loan Servicing Disclosure (MLSD), and the CHARM Booklet are also important disclosures in the mortgage loan process, but they are not specifically required to be provided within 3 days of application under Regulation X. Option A
