DKIM Alignment hinges the domain in your "FROM" header matching the domain used in the DKIM signature (d=domain.com). This uses a relaxed format by default which means that a sub-domain would align as well. If this value is changed to strict in your DMARC record then the domain must match exactly.
If there are multiple DKIM signatures, only one of them must align for DKIM alignment to be valid.
