Answer: A

Like poles repel.

Trap B Reverses a relationship or direction: Write the relationship with an arrow or proportionality sign first (E ∝ f; R ∝ L; cooling a metal → R falls). Then check the option follows the same direction.

Trap C Uses everyday intuition instead of physics: Name the law that applies (Newton's first law, Archimedes' principle, kinetic theory) and reason from it. If the option only 'feels' right, test it against the law.

Trap D Takes part of the condition as the whole answer: Check whether the option is enough on its own. Equilibrium needs zero resultant force AND zero total moment; a complete explanation names every factor in the stem.
