Constitutionality of Preamble

Main difference between the Preamble of our Constitution and a usual Constitution is ki vah hamaare Constitution ka mool-mantra hai. Lekin Constitution kya Preamble ko constitutionality deti hai?

Maine pehle socha tha ki na, lekin phir maine socha ki Preamble hai Constitution ka mool-mantra, aur woh sabhi articles ka base hai. Toh, kya Constitution Preamble ko constitutionality deti hai? Toh, maine kaam se nikaala answer - A. Preamble hai constituent act ke hi anuprastha.

Ab aapka turn hai, kaisa aapka answer hoga?
