**Core Concept**
The question is testing the knowledge of long-acting reversible contraceptive options, specifically Intrauterine Contraceptive Devices (IUCDs). IUCDs are a type of contraceptive that releases hormones or copper ions to prevent pregnancy and are available in various forms with different durations of action.

**Why the Correct Answer is Right**
The Mirena IUCD is a hormone-releasing system that contains the progestin levonorgestrel. It works by thickening the cervical mucus, thinning the uterine lining, and preventing ovulation. The levonorgestrel released by Mirena also has a systemic effect, which helps to reduce menstrual bleeding and cramps. The Mirena IUCD has a lifespan of 5 years, but its successor, the Skyla IUCD, has a lifespan of 3 years, while the Kyleena IUCD has a lifespan of 5 years. However, the Liletta IUCD and the Mirena IUCD have a lifespan of 10 years and 5 years, respectively, but the Mirena IUCD is the one which is available in the market with a lifespan of 5 years. However, the correct answer is the one which has a life span of 10 years.

**Why Each Wrong Option is Incorrect**
**Option A:** Mirena IUCD has a lifespan of 5 years, not 10 years.
**Option B:** Skyla IUCD has a lifespan of 3 years, not 10 years.
**Option C:** Kyleena IUCD has a lifespan of 5 years, not 10 years.
**Option D:** Liletta IUCD has a lifespan of 10 years, which is the correct option.

**Clinical Pearl / High-Yield Fact**
It's essential to note that IUCDs can be effective for up to 10 years, depending on the type. This option is ideal for women who require long-term contraception or have difficulty adhering to daily contraceptive regimens.

**Correct Answer:** D. Liletta IUCD.
