The answer is: D) The objects have the same acceleration.
A high pressure center is generally characterized by cool, dry weather. The movement is cause by the addition of forces due to gravity because their higher pressure compresses the column of air near the center of the area nto greater density and so greater weight compared to lower pressure, lower density and lower weight of the air outside the center.
