Do the two circles with their centres at A and B and having radii $$r_1$$, and $$r_2$$, intersect ?
I. Distance between A and B is ‘a’ units.
II. $$\mid r_1 - r_2 \mid < a < r_1 + r_2$$

A

if the statement I alone is sufficient to answer the question.

B

if the statement II alone is sufficient to answer the question.

C

if both the statements I and II are sufficient to answer the question but neither statement alone is sufficient.

D

if both the statements I and II together are not sufficient to answer the question and additional data is required.
