What is the correct order of soil particle sizes from smallest to largest?

Explanation:
Understanding soil texture involves ordering particle sizes from smallest to largest. Clay is the tiniest, typically less than 0.002 mm, followed by silt at about 0.002–0.05 mm, then sand at roughly 0.05–2 mm, and finally gravel, which is larger than 2 mm. So the sequence from smallest to largest is clay, silt, sand, gravel. The option that matches this exact order is the one that lists clay first and gravel last. Sequences that place larger particles before smaller ones, like gravel before sand, don’t fit because they contradict the actual size ranges.
