Try passing the options variable into the parameters of new FirefoxDriver(). It worked for me like this:

FirefoxOptions options = new FirefoxOptions();
    options.BrowserExecutableLocation = ("C:\\Program Files\\Mozilla Firefox\\firefox.exe"); //This is the location where you have installed Firefox on your machine

   // WebDriver driver = new FirefoxDriver(options);

    using (var FireFoxPage = new FirefoxDriver(options))
    {
   //...

Actually, I see a commented variable using the options object, did you have any errors using it instead?
