B Correct answer
Explanation

Gravel particles are coarse mineral particles ranging from 2mm to 64mm in diameter. They are larger than sand (0.06-2mm) and much larger than clay particles (less than 0.002mm). The term 'coarse particles' accurately describes gravel's size classification in soil particle size analysis.
