Q.	is a curve generated by a point on the circumference of a circle which rolls without slipping on a straight line.
A.	trochoid
B.	epicycloid
C.	cycloid
D.	evolute
Answer» C. cycloid
Explanation: trochoid is curve generated by a point fixed to a circle, within or outside its circumference, as the circle rolls along a straight line. cycloid is a curve generated by a point on the circumference of a circle which rolls along a straight line. ‘epi’ represents the directing path is a circle.
