2) VETO power.
This Veto power is very important in deciding international proposal. Security Council decisions on all substantive matters require the affirmative votes of nine members. A negative vote or "veto" by a permanent member prevents adoption of a proposal, even if it has received the required votes.
Considering 1) India is always being peaceful nation and peace keeper. So India is a rightful nation which should get its seat among permanent members.
2) India never used its power to evil purpose or for selfish purpose or to overthrow its enemies. This again proves India a rightful nation to have its seat reserved among permanent members
