Atmospheric pressure varies with the altitude.

Do you have any reason?

Altitude increases the atmospheric pressure decreases.

Increases with Altitude. Atmospheric Pressure has nothing to do with weather condition or temperature.

I think d is the right answer. Atmospheric pressure at any point is numerically equal to the weight of the air column of the unit x sectional area. Temperature can vary the weight of the air. Weather conditions also vary the weight of air.

A is the answer.
At an elevation of 10 km (6 miles or about 30,000 feet), roughly the height of Mt. Everest, pressure drops to 265 millibars. That's less than 30% of the pressure at sea level! Both atmospheric pressure and the density of air decrease with altitude.

This happens when the temperature of air is increased. Warm air molecules have more energy, so they move faster and create more pressure. Likewise, cold air has less energy and therefore exerts less pressure on its surroundings. The denser the air is, the more molecules there are in that given space.
