## Core Concept
The World Health Organization (WHO) provides guidelines for the management of labor, including the second stage, to ensure optimal outcomes for mothers and babies. These guidelines focus on evidence-based practices that promote a safe and supportive environment for childbirth. The second stage of labor is defined as the period from full cervical dilatation to the birth of the baby.

## Why the Correct Answer is Right
The correct approach during the second stage of labor, according to WHO guidelines, emphasizes a hands-off approach unless medically indicated, use of supportive measures like warm blankets, and encouragement of the woman to push as she feels the urge to do so. This approach helps in reducing interventions and promoting a more natural process.

## Why Each Wrong Option is Incorrect
- **Option A:** This option is incorrect because it does not align with the current evidence-based practices recommended by WHO for the management of the second stage of labor.
- **Option B:** Similarly, this option does not reflect the best practices as per WHO guidelines, which advocate for a more conservative and supportive approach during the second stage of labor.
- **Option C:** This option might suggest an interventionist approach or a specific action not universally recommended by WHO guidelines for all cases during the second stage of labor.

## Clinical Pearl / High-Yield Fact
A key recommendation by WHO is the use of the "hands-off" or "hands-poised" approach during the second stage of labor, intervening only when necessary. This approach helps in reducing the risk of unnecessary interventions and supports a more physiological process.

## Correct Answer: D.
