If C1 & C2 are the Circumferences of Circles With Radii R1 & R2, Then
If C1 + C2 = C3, then the correct answer is
B. R1 + R2 = R3
Detailed Explanation

Consider two small circles with radii R1 and R2. Their circumferences will be C1 and C2 respectively.
Since the circumference of any circle is defined as C = 2πr, for the given circles, C1 = 2πR1 and C2 = 2πR2
Now, consider a third circle whose radius is R3 and circumference is C3. Then C3 = 2πR3
Now, consider C1 + C2 = C3, then substitute their formula to get 2πR1 + 2πR2 = 2πR3 2π(R1 + R2) = 2πR3
Divide both sides of the previous equation by 2π, and we get R1 + R2 = R3 => C1 + C2 = C3, then it implies R1 + R2 = R3.
