Solution
The correct option is D Proteinaceous centre
Starch is formed by α-1,4 linkages between two glucose unit which is broken down during its digestion. It is storage food material of plant cells and is stored in the form of granules. Oval and eccentric starch grains occur in potato which is stored to support the plant during scarcity. These starch grains have a central proteinaceous area called hlium around which the starch is deposited as an oval eccentric layer in potato. So, the correct answer is option B
