Answer:
B & C
Step-by-step explanation:
Hello, the answer to your question would be the above, based off of the common external tangent definition.
A common external tangent does not intersect the line segment joining the centers of circles.
Therefore, viewing the graph, we can deduce that B & C is the correct answer.
The other two are internally tangent, due to the fact they intersect the line segment adjoining the circle centers.
Hope it helps.
