(A) The correct answer is $A$. Lysosomes are single-membraned organelles,not double-membraned. They are small vesicles formed by the budding off from the trans-face of the Golgi apparatus and contain various hydrolytic enzymes (acid hydrolases) that are active at acidic $pH$. The other statements are correct: Endoplasmic reticulum is a network of tubules involved in transport and synthesis; Leucoplasts are plastids that lack pigments and contain $DNA$ and ribosomes; Sphaerosomes are single-membrane-bound organelles involved in lipid metabolism.
