Leucoplasts are colourless plastids found in plant cells. They are primarily involved in the storage of various nutrients. Different types of leucoplasts are specialized for storing specific substances: amyloplasts store starch, elaioplasts store oils or fats, and aleuroplasts (or proteinoplasts) store proteins. The question asks for a plastid that stores starch, oil, and protein granules, and leucoplast is the general category that includes these specific storage plastids.
