   The answer is C usepeerdns

   man ppdd(8)
   usepeerdns
   Ask the peer for up to 2 DNS server addresses. The addresses
   supplied by the peer (if any) are passed to the /etc/ppp/ip-up
   script in the environment variables DNS1 and DNS2, and the
   environment variable USEPEERDNS will be set to 1. In addi‐
   tion, pppd will create an /etc/ppp/resolv.conf file containing
   one or two nameserver lines with the address(es) supplied by
   the peer.

   Please update

   joe and micha are right

   If usepeerdns option is used, pppd will create the /etc/ppp/resolv.conf file with obtained DNS addresses while establishing a connection. By default, the /etc/ppp/ip-up.d/00_dns hook script moves this file to /etc/resolv.conf, allowing the system to use these name servers. If this is undesirable (e.g. you are using a local caching DNS), edit the /etc/ppp/ip-up.d/00_dns.sh as you need.
