The correct answer is: **Grooves are the indentations, whereas ribs are the raised ridges running the circumference of the tire.**Explanation: In tire tread design, grooves refer to the channels or indentations that help with water drainage and traction, while ribs are the raised sections that provide stability and grip on the road surface. This definition accurately describes the relationship between ribs and grooves in a tire's tread pattern.
