A straight line and a circle in a plane can have at most—

aone point in common
btwo points in common
cthree points in common
dfour points in common

ব্যাখ্যা

A circle is a second-degree curve and a straight line is first-degree, so solving them together yields a quadratic equation with at most two real roots. Therefore a line can meet a circle in at most two points.
