B.

C.

D.

Explanation:
A: The evidence in computer crimes usually comes straight from computers themselves. This means the data are held as electronic voltages, which are represented as binary bits. Some data can be held on hard drives and peripheral devices, and some data may be held in the memory of the system itself. This type of evidence is intangible in that it is not made up of objects one can hold, see, and easily understand. Other types of crimes usually have evidence that is more tangible in nature, and which is easier to handle and control.
