In a village with 180 eligible couples , family planning data of contraceptive method is Sterilization: Vasectomy-3, and Tubectomy-8 IUD users-10 Orals pill users-10 Condom users-29 Effective CPR in the village is:

**Core Concept**
Effective Contraceptive Prevalence Rate (CPR) is a measure of the percentage of women of reproductive age (usually 15-49 years) in a population using any form of contraception. It is an important indicator of family planning efforts and reproductive health.

**Why the Correct Answer is Right**
To calculate CPR, we need to divide the number of women using any form of contraception by the total number of eligible couples and multiply by 100. In this case, there are 10 IUD users, 10 oral pill users, and 29 condom users, but we must also consider the sterilized couples (3 vasectomy and 8 tubectomy). Since CPR includes all methods of contraception, we add the sterilized couples to the other users. Therefore, CPR = (10 + 10 + 29 + 3 + 8) / 180 * 100.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option does not provide any calculation or consideration of the sterilized couples, which is a crucial part of CPR.
* **Option B:** This option is not provided, so we cannot evaluate it.
* **Option C:** This option is not provided, so we cannot evaluate it.
* **Option D:** This option is not provided, so we cannot evaluate it.

**Clinical Pearl / High-Yield Fact**
When calculating CPR, remember to include all forms of contraception, including sterilization methods, as they contribute to the overall effectiveness of family planning efforts.
