One circle is drawn completely inside another circle such that no point is common to both the circles. How many common tangent(s) can be drawn?
Explanation:
As shown in the figure, since one circle is completely inside the bigger circle such that no point is common to both the circles.
Hence, any tangent drawn to the inner circle always intersects the outer circle at two points thereby becoming a secant.
∴ No common tangent can be drawn for two circles, where one circle is completely inside the other and there is no point common to both the circles.
Hence, option (a).
