To solve this problem, we need to identify the hormone-releasing Intra-Uterine Devices (IUDs) from the given options. Let's analyze each option:$\newline \bullet$Option 1: Vaults, LNG-20$\newline$ - Vaults are not hormone-releasing IUDs.$\newline$ - LNG-20 is a hormone-releasing IUD that releases levonorgestrel.$\newline$ - Therefore, this option is partially correct.$\newline \bullet$Option 2: Multiload 375, Progestasert$\newline$ - Multiload 375 is a copper-releasing IUD, not a hormone-releasing one.$\newline$ - Progestasert is a hormone-releasing IUD that releases progesterone.$\newline$ - Therefore, this option is partially correct.$\newline \bullet$Option 3: Progestasert, LNG-20$\newline$ - Progestasert is a hormone-releasing IUD that releases progesterone.$\newline$ - LNG-20 is a hormone-releasing IUD that releases levonorgestrel.$\newline$ - Therefore, both items in this option are hormone-releasing IUDs, making this option correct.$\newline \bullet$Option 4: Lippes Loop, Multiload 375$\newline$ - Lippes Loop is a non-hormonal IUD.$\newline$ - Multiload 375 is a copper-releasing IUD, not a hormone-releasing one.$\newline$ - Therefore, this option is incorrect.$\newline$Based on the analysis, the correct option is Option 3: Progestasert, LNG-20.
