The required filename needs a static prefix, runtime date tokens, and a monthly resetting sequence. The correct Workday-style pattern uses bracketed date tokens: [yyyy] for the four-digit year and [MM] for the two-digit month. The sequence token [seq] supplies the next sequence number. Because the sequence must be five digits, Padding must be set to 5 so values appear as 00001, 00002, and so on. Restart Frequency must be Month because the sequence resets at the beginning of each new month. Option B incorrectly treats the tokens as literal text and resets yearly. Option C uses invalid token names and resets daily. Option D uses nonstandard token names and lacks the required five-digit padding.
