Thank you for reference but the derivation of multiple stocks is required not a single one. KIndly guide in this regard. I got detail about the topic but derivation for the equation and solution is not clear.
Thanks.

Your question is not completely clear. Do you mean put-call symmetry? Because there is a lot of symmetry in option pricing. But always a good idea is to consult the book written by Steven Shreve on mathematical finance, and especially part 2 of the two-volume book.
Sir J. W. Nieuwenhuis, in this book, the derivation for multiple stocks is not clear. Please give me a reference where the derivation for multiple stocks is given.
x-K= max{x-K,0} - max{K-x,0}. Based on this simple identity one easily derives
put-call parity for European options. Maybe this identity helps.
Of course one has to assume markets that are liquid, without transaction costs , and are arbitrage-free as well.
Also have a look at :
