Explanation

mysqldumpslow is the correct utility - it was built specifically to parse MySQL's Slow Query Log and summarize/sort entries by metrics like query time, average query time, and execution count, making it easy to identify problematic queries.

Why the distractors are wrong:

B. mysqldump - exports database data/schema for backups; it knows nothing about query logs.
C. mysqlaccess - checks and reports user access privileges; unrelated to performance analysis.
D. mysqlshow - displays metadata about databases, tables, and columns; not a log analysis tool.
E. mysqlslow - this utility does not exist; it's a plausible-sounding fabrication.

Memory tip: Break the name apart - mysqldumpslow = "dump (summarize) the slow queries." The word slow in the name directly maps to the Slow Query Log, making it the only logical choice.
