Stability depends on center of mass height Steps:

• Equal base areas mean identical support widths for tipping.
• Stability increases as center of mass (COM) height decreases for fixed base.
• Compare COM heights across shapes: lowest COM resists tipping best.
• Identify object with highest COM as least stable.

Why C is correct:

• C has the highest COM relative to base, reducing tipping angle per torque equilibrium (∑τ = 0 when COM projection exits base).

Why the others are wrong:

• A: Low COM from uniform squat shape ensures wide stability margin.
• B: Moderate COM height provides better balance than C.
• D: Lowest COM in compact form maximizes resistance to overturning.

Final answer: C
