Answer:
The answer in one common tangent only ⇒ answer (B)
Explanation:
∵ The two circles touch internally in a common point
* At this point we can draw only one tangent
∵ This point is common in the two circles
∴ The tangent will be common for the two circles
∴ There is only one common tangent can be draw passing
through the common point which the two circles
touch each other on it
∴ The answer is (B)
