**Core Concept**
The question is testing the knowledge of different types of Intrauterine Contraceptive Devices (IUCDs) and their lifespan. IUCDs are a type of long-acting reversible contraceptive (LARC) that release hormones or copper to prevent pregnancy. They are a popular choice for women seeking effective and long-lasting birth control.

**Why the Correct Answer is Right**
The Mirena IUCD is a hormone-releasing IUCD that contains the progestin levonorgestrel. It works by thickening the cervical mucus, preventing sperm from reaching the egg, and thinning the uterine lining, making it difficult for a fertilized egg to implant. The Mirena IUCD is designed to last for 5 years, but a newer version called the Liletta IUCD, also contains levonorgestrel, and is approved for use up to 10 years. This is the correct answer because it has the longest lifespan among the given options.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify a particular IUCD model that lasts for 10 years.
**Option B:** This option is incorrect because the IUCD model mentioned does not have a lifespan of 10 years.
**Option C:** This option is incorrect because the IUCD model mentioned does not have a lifespan of 10 years.

**Clinical Pearl / High-Yield Fact**
It's essential to note that IUCDs are a highly effective form of birth control, with a failure rate of less than 1%. They are also a popular choice for women with heavy menstrual bleeding, as they can help reduce bleeding and alleviate symptoms.

**Correct Answer:** C. Liletta IUCD
