Which of the following pair (s) of circles have / as a common external tangent? Select all that apply.

A and B

A and C

B and C

A and B

A and C

Step-by-step explanation:

Common internal tangents intersect the segment joining the centers of the two circles.

Tangent I is common internal tangent to circles A and B as the line joining the centers of circles will intersect the tangent I.

Tangent I is also a common internal tangent to circle A and C. The line joining the centers of circles A and C intersects tangent I.

Tangent I is not a common internal tangent to circles B and C,
