(A) is true. Carbon source such as sucrose is used in the nutrient medium. 

(R) is true. Capacity to generate a whole plant from any cell/explant is totipotency. 

(R) does not explains (A). Capacity to generate whole plant from any cell/explant is the in situ property of plants. Supply of glucose in the nutrient medium is not reason for totipotency of plant.
