Which IPv4 address is in correct format?

IPv4 addresses are written as four decimal numbers (octets) separated by dots, with each octet ranging from 0 to 255. In the given options, the one with 400 in the third octet exceeds the allowed maximum, so it’s not valid. The one with letters in an octet isn’t a numeric value, so it can’t be an IPv4 address. The one with 286 in the third octet also exceeds 255. Since none of the four-octet formats meets the rule, none of the above are valid IPv4 addresses.
