Increasing the object-to-image distance (OID) from 1 inch to 2 inches will result in:

Increasing the object-to-image distance (OID) from 1 inch to 2 inches will lead to decreased spatial resolution. Spatial resolution refers to the ability of an imaging system to distinguish between small details in the image. When the OID increases, the image produced is more susceptible to blurring because the x-rays diverge more as they travel from the object to the imaging receptor.

A larger OID increases the distance that the x-ray photons travel before reaching the image receptor, which can result in a less defined image. This blurring effect happens because the increased distance allows the rays to spread out more, leading to a loss of sharpness in fine details. Consequently, the overall quality of the image diminishes, leading to a decrease in spatial resolution.

Therefore, altering the OID to a greater distance negatively impacts the clarity and detail visible in radiographic images, which is why this option is the correct choice.
