Answer 1

The correct option is D Vacuoles

• Colour of rose petals is due to water-soluble pigment present in the vacuoles.
  
• The plant vacuoles consist of various water-soluble pigments such as carotenoids, anthocyanins and xanthophylls etc.
• Anthocyanins are also water-soluble pigments which are red, purple, or blue in colour depending on the pH (blueberry, raspberry etc).
  
• The colour of flower petals (red, pink, blue and purple) is mainly from the pigments called anthocyanins.
  
• So, the correct answer is 'Vacuoles'.
