Answer
(A) is true, but (R) is false.
Reason —
Assertion (A) is true because a rainbow is indeed a natural spectrum that appears when sunlight is dispersed by water droplets in the atmosphere and the white light of the sun splits into its seven constituent colours — violet, indigo, blue, green, yellow, orange, and red.
Reason (R) is false because a rainbow is not formed when the sun is overhead but it is formed when the sun is low in the sky, usually in the morning or evening and water droplets from rain or mist are present opposite the sun.
Hence, (A) is true, but (R) is false.
