How many possible scan results are there?

How many possible scan results are there?

• A. 3
• B. 6
• C. 5
• D. 4

Answer: (C)

In this kind of question, the number of possible scan results equals the number of distinct outcomes the scan can produce. If there are five different result categories the scan could land in, then there are five possible results, because each individual scan produces exactly one category. The other numbers would only be possible if there were a different number of categories. So five is the correct count.
