Answer: Option A

The pink colour in the skin of the radish root is due to Anthocyanin.
Root skin colour is one of the economically important traits in radish (Raphanus sativus), and the pigmentation in red skin varieties is largely attributable to anthocyanin accumulation. Pelargonidin was found as a major anthocyanin pigment accumulated in the sub-epidermal layer of red radish roots.
