As part of the certificate issuance process from the CA that her company works with, Maria is required to prove that she is a valid representative of her company. The CA goes through additional steps to ensure that she is who she says she is and that her company is legitimate, and not all CAs can issue this type of certificate. What type of certificate has she been issued?

Extended Validation (EV) certificates verify that the X.509 certificate has been issued to the accurate legal entity, and only particular certificate authorities (CAs) have the authority to issue EV certificates. Domain-validated certificates require evidence that the domain is under your control, such as by setting the DNS TXT record or responding to an email sent to a contact in the domain's Whois record. An organizational validation certificate mandates domain validation and additional verification that the organization is a legal entity. OCSP certificates are not a suitable option for this question.
