D. Install the certificate chain to the AEM truststore
Explanation:
AEM Desktop needs to establish a secure connection to the AEM Author instance over SSL. If the intermediate certificate is installed on Apache but not recognized by AEM, the truststore must be updated. AEM maintains a truststore to store trusted SSL certificates, including intermediate and root certificates, allowing secure communication with external systems.
By installing the certificate chain (which includes the root and intermediate certificates) into the AEM truststore, the AEM Desktop application will be able to establish a trusted SSL connection to the AEM Author instance.
