Based on the given question above, the correct answer would be option A. Even though cells contain specialized parts, known as organelles, to perform specific tasks, such as waste disposal, protein building, and movement, all cells do not perform the same exact functions in multicellular organisms. Multicellular organisms contain many cells, so these organisms have specialized cells that perform different functions. The specialization of cells in multicellular organisms allows them to operate more efficiently. Hope this helps.
