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,
So,
We simply invert and multiply.

Re-arrange the numbers so that they are easier to understand.
