The correct answer is: B. is in ascending order.
A list in alphabetical order is a list of items that are arranged in order of their first letter, from A to Z. This is an example of ascending order, which is a way of ordering things from smallest to largest or from lowest to highest.
Option A is incorrect because a list in alphabetical order is not in descending order. Descending order is a way of ordering things from largest to smallest or from highest to lowest.
Option C is incorrect because a list in alphabetical order is not necessarily the result of a sort operation. A sort operation is a process of arranging data in a specific order. However, a list in alphabetical order can be created in other ways, such as by manually typing the items in order.
Option D is incorrect because only option B is correct.
Option E is incorrect because option B is the correct answer.
