A. Create a new standard primary zone on each branch office DNS server for the new domains. Configure forwarders on the main office DNS servers to point to the branch office servers.
B. Create a new stub zone on each branch office DNS server for the new domains. Configure conditional forwarders on the main office DNS servers to point to the branch office DNS servers.
C. Configure a delegation subdomain DNS record on the main office DNS server for each new domain. Configure a stub zone on each branch office DNS server for the new domains. Configure zone transfer for the contoso.com zone to the branch office DNS servers.
D. Configure a delegation subdomain DNS record on the main office DNS server for each new domain. Create a new standard primary zone on each branch office DNS server for the new domains. Configure zone transfer for the contoso.com zone to the branch office DNS servers.

then configure zone transfer for the Contoso.com zone to the branch office DNS servers after installing DNS server in each branch office.
In DNS, a subdomain is a portion of a domain that you’ve delegated to another DNS zone. A subdomain is configured when you need to create domains in existing domain. A company might use subdomains for its various divisions. Because, to migrate your DNS zone data for the Contoso.com zone to the branch office DNS servers, you will need to have a functioning standard primary server, you will need to create a new standard primary zone on each branch office DNS server for the new domains.
