Answer: D. Statement I is false but Statement II is true.

Correct answer is D — Statement I is false, Statement II is true.

Why D is correct: Statement II is well-supported: warming expands the geographic range and transmission season of vector-borne pathogens (malaria, dengue, chikungunya, Lyme), enables waterborne outbreaks (cholera) after floods, and thaws permafrost that can release dormant microbes — IPCC AR6 WG-II flags rising infectious-disease burden with high confidence. Statement I overreaches by lumping "human infrastructure" with organisms: humans actively engineer adaptation (sea walls, climate-resilient design, managed retreat, AC, irrigation), so the blanket claim that infrastructure "will not be able to move or adapt" is treated as false; the accepted IPCC framing is that *many organisms and natural ecosystems* cannot keep pace, not human-built systems.

A: Wrong because it accepts Statement I, which incorrectly denies humans' capacity to adapt infrastructure.
B: Wrong because Statement II is firmly supported by IPCC and WHO evidence on climate-sensitive diseases.
C: Reverses the truth values — it is II that is true, not I.

Paper 1 tip: For NET, remember the IPCC distinction — natural species/ecosystems face adaptation limits (range shifts, phenology mismatch), while human systems have engineered adaptation pathways (though with cost and equity limits). Climate–health link (vector range expansion, heat stress, water/food-borne disease) is a recurring true-statement template.
