Explanation

c) Leucoplasts:Leucoplasts are a third type of plastid found in plant cells. They are non-pigmented and play a role in storing or synthesizing various substances. There are different types of leucoplasts, including amyloplasts (which store starch), elaioplasts (which store oils and lipids), and proteinoplasts (which store proteins).
