Estrogen promotes deposition of subcutaneous fat in the gluteofemoral region (hips, thighs, buttocks), producing the classic "pear-shaped" or gynoid fat pattern.

1) Relevant knowledge points and concepts
- Body fat distribution shows sexual dimorphism: women typically exhibit a gynoid (pear) pattern, men an android (apple) pattern.
- Sex hormones regulate fat distribution: estrogen favors subcutaneous fat storage in the hips and thighs; testosterone promotes visceral abdominal fat.
- Menopause reduces estrogen levels, often shifting women from a gynoid to a more android (central) pattern.

2) Step-by-step reasoning
- Identify the fat pattern described: "pear shape" = fat concentrated in hips, thighs, buttocks = gynoid distribution.
- Determine which population typically displays gynoid distribution: because estrogen drives subcutaneous gluteofemoral fat, populations with higher estrogen (premenopausal women) show this pattern.
- Consider alternatives: postmenopausal women have decreased estrogen, so they tend to accumulate more abdominal (android) fat. Men (both younger and older) are more likely to show android distribution due to higher androgen influence.

3) Calculations/intermediate steps
- Not applicable because this is a conceptual physiology question without numerical calculations.

4) Why the correct answer is correct
- Younger (premenopausal) women have relatively high estrogen levels that direct fat storage to the hips and thighs. This hormonal effect creates the characteristic pear shape seen in that group.

5) Why the other options are incorrect
- Older (postmenopausal) women: reduced estrogen leads to more central/visceral (apple) fat, not pear shape.
- Older men and younger men: males typically display android (abdominal) fat distribution due to androgen influence, not a pear-shaped pattern.

6) Conclusion
Therefore the pear-shaped fat distribution is typical of younger (premenopausal) women, which matches the provided correct answer.
