To perform analysis of key values by the server, the statement used is . . . . . . . .

This question is asking about how you tell MySQL to gather information about the indexes (key values) within your tables.
Think of it like this: Imagine you have a big box of toys, and you want to know how many of each type of toy you have (like cars, dolls, or blocks). To figure this out, you'd need to go through the box and count them.
MySQL uses the ANALYZE TABLE command to do the same thing for its indexes. It goes through the table's indexes and gathers information like:
* How many entries are in each index * How the entries are organized * Whether there are any problems with the index
This information helps MySQL optimize queries (how it searches through your data) and make things run faster.
So the answer is Option B: ANALYZE TABLE
