Arrange the following human body parts in logical order from head downward: (a) Chest (b) Forehead (c) Stomach (d) Ears (e) Legs (f) Chin.

Introduction / Context:
Logical sequence problems often ask for spatial ordering. Here we align body parts from the top of the head down to the feet. Visualizing a head-to-toe scan avoids confusion.

Given Data / Assumptions:

• Top-of-head/face: Forehead (b), Ears (d), Chin (f)
• Torso: Chest (a), Stomach (c)
• Lower limbs: Legs (e)

Concept / Approach:
Move from the highest anatomical landmark to the lowest, respecting normal human anatomy in upright posture. Within the head area, the forehead lies above the ears and chin; ears are roughly lateral to eyes but still above the chin; the chin is below both. Then come chest and stomach (abdomen), followed by legs.

Step-by-Step Solution:
1) Forehead (b) — highest among listed head/face parts.2) Ears (d) — above the chin; head level.3) Chin (f) — bottom of the face.4) Chest (a) — upper torso.5) Stomach (c) — below chest.6) Legs (e) — below torso.

Verification / Alternative check:
Mentally draw a stick figure and label positions. Reading from top to bottom yields b → d → f → a → c → e.

Why Other Options Are Wrong:
They either start at mid-torso (a), misplace head parts, or reverse torso order (stomach before chest).

Common Pitfalls:
Equating lateral position (ears at sides) with vertical order; remember we order vertically, not by left/right position.

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