Fenestrated capillaries form the blood-brain barrier.

Explanation:

The fenesterated capillaries are small fine thin capillaries that helps in the exchange of substances. These capillaries are mainly found in the kidney, small intestine and glands.

The fenestrted capillaries allow the exchnage of hormone in the blood and in the kidney for the filtration. The nutrients can be easily exchanged by the capillaries present in the small intestine. The blood brain barrier function is not performed by the fenesterated capillaries. They allows the rapid exchange function and not as the barrier.

Thus, the correct answer is option (D).
