If C1 and C2 are the circumferences of the outer and inner circles respectively. What is C1 : C2? I. The two circles are concentric. II. The area of the ring is 2/3 the area of greater circle.

if statement I alone is sufficient to answer the question.
if statement II alone is sufficient to answer the question.
if both statement I and II together are necessary to answer the question.
if both statement I and II together are not sufficient to answer the question.
