Which of the following lists license classes mentioned in the material?

• A. A, B, C, D
• B. a, b, c, d
• C. 1, 2, 3, 4
• D. License Classes A through D

Answer: (D)

The idea being tested is how the material names the group of license categories. The material presents this group as “License Classes A through D,” which explicitly lists both the category (License Classes) and the full range (A through D). That exact phrasing directly matches how the material describes the set, making it the correct choice.

The other options don’t fit because they present the elements in forms that don’t align with the described naming: single uppercase letters alone, lowercase letters, or numbers don’t reflect the category and range as stated.
