Which of the following is included in an electronic notarial certificate?

The inclusion of the electronic notary public's electronic signature and seal in an electronic notarial certificate is crucial for validating the document's authenticity in the digital realm. An electronic signature certifies that the notary has completed the notarial act, while the electronic seal serves to confirm the notary’s identity and authority. Both elements are essential components that uphold the integrity and legal standing of electronically notarized documents, much like physical signatures and seals do for traditional notarial acts.

The other options do not align with the requirements of an electronic notarial certificate; a physical signature and corresponding ID would be relevant in traditional notarizations but not in the context of electronic notary practices. Including a statement about the notary’s working hours is not standard and does not pertain to the certification of the notarial act itself. Lastly, the use of a physical seal and ink signature pertains to traditional methods rather than the electronic format, which requires specific digital identifiers. Thus, option C is the only one that accurately reflects the essential elements of an electronic notarial certificate.
