Based on the statement provided, the correct answer is:
(A) True
Explanation:
1. Notarizing a document involves a notary public certifying the authenticity of the signature on a document.
2. If someone is unable to sign their name, the notary public cannot verify their identity through the signature.
3. Without a valid signature to notarize, the notary public cannot proceed with the notarization process.
4. Therefore, if someone cannot sign their name, the notary cannot notarize a document for them, making the statement true.
