Why each option
A DNS forward lookup zone resolves hostnames to IP addresses, which is the standard direction of DNS name resolution.
Converting IP addresses to hostnames is the function of a reverse lookup zone, which uses PTR records.
A forward lookup zone in DNS stores A (and AAAA) records that map human-readable hostnames to their corresponding IP addresses. When a client queries DNS for a hostname such as 'server.domain.com', the forward lookup zone provides the associated IP address, enabling network communication.
Converting MAC addresses to IP addresses is performed by ARP (Address Resolution Protocol), not DNS.
Converting IP addresses to MAC addresses is also the role of ARP, not a DNS function.
