If a straight line touches a circle at exactly one point, the line is called—

aa chord
ba secant
ca tangent
da radius

ব্যাখ্যা

A line meeting a circle at exactly one point grazes its edge without crossing into the interior, which is the defining property of a tangent. A secant would cut it at two points, and a chord joins two points on the circle.
