Why does a precision scale give different readings for the weight of an object in air and in a vacuum (remembering that weight is the force exerted against a supporting surface)? Provide an important consideration when weighing objects in both environments.

a. The presence of air resistance affects the weight of the object
b. Gravity is stronger in a vacuum, leading to a different weight measurement
c. The buoyancy force of the air affects the weight measurement in different environments
d. The accuracy of the scale may be affected by the presence of air particles
e. Objects may have different properties in a vacuum, affecting their weight measurement
