Correct answer & explanation

Inbound DNS policy
An inbound DNS policy forwards DNS queries from on-premises DNS servers to Cloud DNS, enabling resolution of private zone names. Option B (Outbound DNS policy) is for forwarding queries from VMs to on-premises DNS, the opposite direction. Option C (Cloud NAT) provides outbound internet access for VMs, not DNS resolution. Option D (Private Google Access) allows VMs with internal IPs to reach Google APIs, not on-premises DNS resolution.
