「江氏門業公司」設有 JDoors.com 網站。這家公司去年推出了支援 Android 和 iOS 裝置的行動應用程式，並鼓勵使用者從網站改用功能更先進的應用程式。該公司目前在 YouTube 和其他數個網站放送廣告，但客戶點選廣告後卻會前往 JDoors.com，而不是開啟應用程式。 哪一項網路技術可以直接在行動應用程式中開啟產品網址？

Deep linking is the correct answer because it allows a user to click on a URL and be taken directly to specific content within a mobile application, bypassing the mobile website. This is precisely what JDoors.com needs to direct users from their ads to their app. HTML5 is a markup language for structuring web content, not a technology for directly opening app content from ads. Two-factor authentication is a security process, unrelated to linking to app content. Universal links (iOS) and Android App Links (Android) are specific implementations of deep linking, but "deep linking" is the overarching concept that directly addresses the problem described.
