Suggested Answer: AD 🗳️
Route 53: 2 public zones and 2 private zones and 4 load balancers: 2 public and 2 internal. This will allow one domain to be balanced over two application servers which will then have traffic balanced to the two backend servers.

Technically, a single private zone shall be enough due to "different domains" shall be more about the external-facing which is the public zones in this case.

Route53 is the only service which provides 100% SLA. This means we don't need to have 2 hosted zones. Not sure, why there are two hosted zones required.
