If statement always executing even when the condition is false???

when it gets to this if statement, no matter what 'option' is inputted its always setting if(option == "y" || "Y") condition to true?

bool UserInterface::readInConfimDeletion() const
{
        string option = "";
        cout << "Are you sure you want to delete these transactions? Y/N "; 
        cin >> option;

        if (option == "y" || "Y")
        {
                return true;
        }
        else if (option == "n" || "N")
        {
                return false;
        }
        else{
                readInConfimDeletion();
                }

}
