• D. (d)

Answer 1

The correct option is B (c)

Membrane bound organelles are found in only eukaryotic cells, these structures include the nucleus, the endoplasmic reticulum (both the smooth and the rough endoplasmic reticulum), the Golgi apparatus, vacuoles, mitochondria, lysosomes (found in animal cells), and chloroplasts (found in plant cells).
