उत्तर
A is false but R is true.
Explanation:
Congruent circles are circles that have the same radius but do not necessarily have the same center; hence, they are not always concentric. Concentric circles, by definition, have the same center but different radii. Therefore, the assertion that congruent circles are concentric is false, but the reason that concentric circles have the same center with different radii is true.
