Explanation

The correct Cisco NX-OS syntax for configuring EIGRP MD5 authentication using a key-chain on an interface is: 'ip authentication key-chain eigrp <key-chain-name> <AS-number> <key-chain-name>' - but more precisely, the required format visible in the answer is 'ip authentication key-chain Pallini EIGRP Pallini', where 'Pallini' is the key-chain name defined in the router configuration and 'EIGRP' is the routing protocol keyword, with the AS number context provided by the exhibit. Options A, B, and C all have the keyword order wrong. Option D matches the syntax required by the exhibit's key-chain and EIGRP configuration.
