The correct option is C Chloroplasts are disintegrated and get converted into Chromoplast
Chloroplasts are green in colour and Chromoplasts are pigmented plastids that are not green in colour. Chromoplasts are usually yellow, red and appear in fruits, flowers or ageing leaves of the plant parts. Interconversion of plastids results the disintegration of chloroplast and its convertion into chromoplasts of different colours.
