(A) is false and (R) is true
Reason — (A) is false because leukoderma is not blood cancer; it is a skin condition in which loss of pigmentation occurs. Blood cancer is called leukaemia, and it involves an abnormal increase in the number of white blood cells. Therefore, (R) is true.
Hence, (A) is false and (R) is true.
