Answer 1

Ans all vegetables, and whole grains etc contain complex sugars hence potato contains complex sugars.

Complex sugars contain more than 1 sugar units. Eg disaccharides.

Simple sugars are monosachharides and reducing sugars like glucose, fructose, sucrose, lactose etc. So food items such as glucose, apple which contains fructose, milk which contains lactose all contain simple sugars.
