Alternate approach — Chronological timeline:
Instead of recalling each pairing independently, arrange the four laws along a timeline of India's environmental legislation. The Wildlife (Protection) Act came first in 1972, followed by the Water (Prevention and Control of Pollution) Act in 1974, then the Forest (Conservation) Act in 1980, and finally the umbrella Environment (Protection) Act in 1986, enacted after the Bhopal gas tragedy to consolidate environmental regulation.
Placing each Act at its correct point on this historical timeline and reading off the corresponding year for each reproduces the same year assignments as List-II, confirming that option (A)-(II), (B)-(I), (C)-(III), (D)-(IV) correctly pairs each Act with its enactment year.
