If you want to specify who can sign a document and include instructions for the signer, what should you do?

A) Inspect the document
B) Insert a digital signature line.
C) Check for authenticity.
D) Acquire a digital ID.

Inserting a digital signature line allows you to specify who can sign the document and include instructions for the signer. This also allows for the document to be signed digitally and securely verified. Inspecting the document and checking for authenticity are important steps in ensuring the document is legitimate, but they do not provide instructions for the signer. Acquiring a digital ID may also be necessary for signing a document digitally, but it does not allow you to specify who can sign the document or provide instructions for the signer.
