A&C
8.4 and above os support both MD5 & IPsec for ospfv2, so if choice is one then only C IPsec is correct. unless they ask for two option.
so correct answer=C
Question is “OSPFv2 and OSPFv3”. and this is single option select question. So i think “C” is reasonable answer.
Note: OSPFv3 does not have a built-in authentication method and relies on IP Security (IPsec) to provide this functionality.
