Concept:Heavy rainfall and lightning are natural weather events; their likely effects are physical, not financial policy decisions.
Explanation:City X has experienced continuous lightning and heavy rain for two days, and more rain is predicted in the next
48Â hours.
Effect I: Raising electricity tariff by
50 paise per unit is an administrative and financial decision, unrelated to weather conditions, so it is not a valid effect.
Effect II: Continuous heavy rain can overwhelm drainage systems, causing water-logging in many areas, which is a direct and immediate consequence.
Effect III: Lightning and strong winds accompanying the rain can uproot trees; falling trees on roads could easily injure people, making it a plausible effect.
Thus, only Effects II and III follow logically from the cause.
Answer:Both II and III are possible effects.
Correct option: C.
