Explanation:

• Light microscopes can visualize the shape and arrangement of bacteria (so option A is incorrect).
• Their resolution limit is ~0.2 micrometers, which prevents them from resolving detailed internal cellular structures like organelles such as ribosomes or the internal membrane systems of mitochondria, making options B and D correct, while option C's 2 micrometer limit is inaccurate.

Answer:

B. Light microscopes are not able to show detailed internal cellular structure.
D. Light microscopes have a resolution limit of 0.2 micrometers.
