The rule of magnetism illustrated is the field lines are more concentrated at the poles and also about the direction of magnetic field.
Explanation:
- Every magnet has two pole, north pole and south pole. The like poles repel each other and unlike poles attract each other.
- The direction of magnetic field is from north to south that can be seen by the iron filling experiment.
- When the iron fillings are kept near the bar magnet, we observe that most of the fillings are attached to either poles.
- It is due to the fact that the concentration of magnetic field is highest at the poles.

Answer: Option A

Tadpoles and aquatic frogs excrete the nitrogen as ammonia, but most terrestrial adults excrete it mostly as urea which is less threatening substance. A few tree frog species with little water access excrete the still less harmful uric acid.
