B. it is surrounded by mountains.

Mexico City lies in a high-altitude basin ringed by mountains. That topography traps pollutants and promotes temperature inversions, preventing polluted air from dispersing. Combined with heavy vehicle and industrial emissions and strong sunlight (which forms photochemical smog), this makes air pollution a major problem.
