The various parts of plants like tissues, roots, stems, fruits etc. contains anthocyanins. Anthoxanthins are clear, white to yellow counterparts of anthocyanins occurring in plants. Anthocyanins are derived from anthocyanidins by adding sugars. The most evident compartment in most plant cells is a large, fluid-filled vesicle, called vacuole in which anthocyanin remains confined. Thus the correct answer is option B.
