"In a connectionless service, there is no setup and teardown phases. Each packet is independent from every other packet. ... IPv4 provides a connectionless service;IPv6 normally provides a connectionless service, but it can provide a connection-oriented service if flow label field is used."

OPTION A -> WRONG . BOTH HEADER SIZE IS NOT SAME .

OPTION B -> STUPID STATEMENT . IPV4 and IPV6 are address classifications, not protocols. The protocols used in them can be classified as connection oriented or connection less. Suppose if  you use TCP in ipv4 or 6  then it is connection oriented, while UDP is connection less.

answer should be D
