Explanation
"Undulate" means to move with a smooth wavelike motion, to rise and fall like waves. "Ripple" captures this sense of wave-like movement. The other options are unrelated: "exterminate" means to destroy, "motivate" means to encourage, and "grapple" means to struggle or wrestle.
AI explanation
Undulate means to move in a smooth wave-like motion, so ripple captures that meaning best. Exterminate (destroy), motivate (inspire), and grapple (struggle/wrestle) are unrelated meanings that don't involve wave-like movement.
