Arrange the following human body parts from bottom (feet) to top (neck): b) Feet c) Knee e) Waist a) Stomach f) Chest d) Neck Select the correct bottom→top sequence.

Introduction / Context:
This problem orders body parts along the vertical axis. Since the prompt does not specify direction, we clarify: arrange from bottom (feet) upward to the top (neck). Knowing approximate anatomical positions allows a single consistent ordering.

Given Data / Assumptions:

• Feet are the lowest point listed.
• Knees sit above feet.
• Waist is above knees and below the stomach.
• Stomach (abdomen region) is above the waist.
• Chest is above the stomach.
• Neck is above the chest.

Concept / Approach:
Move along the body from inferior (lower) to superior (upper) parts. At each step, confirm relative position to avoid skipping levels.

Step-by-Step Solution:
Lowest: b) Feet.Then: c) Knee.Next: e) Waist.Then: a) Stomach.Then: f) Chest.Top: d) Neck.Sequence: b, c, e, a, f, d.

Verification / Alternative check:
Cross-check adjacent pairs (e.g., chest above stomach, neck above chest) to ensure monotonic ascent.

Why Other Options Are Wrong:

• c, e, f, a, d, b: mixes top and bottom; ends at feet.
• d, c, f, a, e, b: starts at neck; immediately jumps to knee.
• f, b, c, d, a, e: misplaces torso vs limbs.
• None of these: not required; a correct sequence exists.

Common Pitfalls:
Confusing stomach and waist ordering or starting at the top inadvertently.

Final Answer:
b, c, e, a, f, d
