Turmeric powder is obtained from which part of turmeric plant?

Correct answer: (d) None of the above

Explanation

Turmeric (Curcuma longa) of the ginger family yields its powder from the dried, underground rhizome – a modified stem, not a true root or seed.

The rhizome is rich in curcumin, giving the yellow colour and anti-inflammatory properties; it is boiled, dried and ground into powder.

Since the source is a rhizome (stem), "dried root", "dried foot" and "seed" are all incorrect, making None of the above the answer.
