Explanation

search and nameserver are the two valid directives in /etc/resolv.conf. nameserver specifies the IP address of a DNS server to query (up to 3 entries allowed), while search defines a list of domain suffixes to append when resolving short hostnames (e.g., search example.com lets you reach host as host.example.com).

The distractors are all invalid: substitute, lookup, and method are not recognized directives in /etc/resolv.conf - lookup and method appear in some BSD variants or older systems but are not standard Linux /etc/resolv.conf keywords.

Memory tip: Think "NS" - the two answers start with letters from Nameserver and Search, the two most fundamental DNS configuration concepts: where to ask (nameserver) and what suffix to try (search).
