Answer:

Option (C).

Explanation:

The dilation of feeder arterioles carry blood directly into the blood vessels. The pre capillary sphincter in the systemic capillary beds can open due to the different factors.

The local release of histamines do not cause the dilation of feeder arterioles and does not cause the opening of systemic capillary beds. Histamine chemical is involved in the immune response of the body.

Thus, the correct answer is option (C).
