**Core Concept**
Kegel exercises, also known as pelvic floor exercises, are a type of physical therapy that targets the muscles of the pelvic floor. These exercises are essential for women to strengthen the muscles that support the bladder, uterus, and bowels, improving bladder control, and enhancing overall pelvic floor health.

**Why the Correct Answer is Right**
The correct answer is based on the principle of allowing the perineal wound to heal before initiating any physical therapy. Kegel exercises involve contracting and releasing the pelvic floor muscles, which can put additional stress on the perineal wound, potentially leading to delayed healing or complications. Therefore, it is essential to wait for a specific period after a normal vaginal delivery to allow the perineal wound to heal before starting Kegel exercises.

**Why Each Wrong Option is Incorrect**
* **Option A:** Immediately after delivery, the perineal wound is still vulnerable to infection and complications. Starting Kegel exercises too soon can exacerbate these issues.
* **Option B:** There is no specific timeframe mentioned in medical literature for initiating Kegel exercises after a normal vaginal delivery. However, it is generally recommended to wait until the perineal wound has fully healed.
* **Option C:** This option is incorrect because the perineal wound typically takes 6-8 weeks to fully heal after a normal vaginal delivery.

**Clinical Pearl / High-Yield Fact**
It is essential for healthcare providers to educate postpartum women on the importance of perineal wound care and the timing of initiating Kegel exercises to prevent complications and promote optimal pelvic floor health.

**Correct Answer: C.**
