Excessively dark radiograph will result from

Overexposure
Excessive millimperage
Underexposure
Insufficient millimperage

The correct answer is: Overexposure

When taking a radiograph, the amount of time and radiation intensity plays important role in the quality of the image produced. If the exposure is too high, it is considered as overexposure, which results in an excessively dark radiograph. This is because the film or sensor was exposed to too much radiation, causing the image to be too dense and difficult to interpret. On the other hand, options B, C, and D all refer to underexposure, meaning that the image produced will be too light or lacking in detail. This can be caused by using insufficient radiation (Option D) or not enough exposure time (Options B and C). Therefore, these options are incorrect as they refer to a different issue than what the question is asking.
