Elaioplast - Storage of fat - Elaioplasts are a particular kind of plastid called a leucoplast that is designed specifically for lipid storage in plants. Round plastoglobuli, or fat droplets, known as elaioplasts, store oil body deposits. Hence The elaioplast holds fat.
Aleuroplast is a leucoplast kind of plastid that is specifically designed for the storage of proteins in plants.
Amyloplasts are a kind of plastic that is used to store starch. Roots and storage tissues include amyloplasts, which synthesize and store starch for the plant by polymerizing glucose. Hence Starch is stored by amyloplasts.
Chromoplast is a colored plastid that is not a chloroplast and often contains a yellow or orange pigment. Consequently, chromoplasts in plants preserve color.

In the light of the above statements, choose the correct answer from the options given below
Alcohol is formed when a saturated carbon atom bonds to a hydroxyl (-OH) group. It is an organic compound that contains a hydroxyl functional group attached to a carbon atom.
Phenol is formed when the -OH group replaces the hydrogen atom in benzene. It is an organic compound in which a hydroxyl group directly attaches to an aromatic hydrocarbon.
Ether is formed when oxygen atom bonds to two alkyl or aryl groups. It is an organic compound that has an oxygen atom that is connected to two aryl and alkyl groups.
