Answer:
The correct answer is allergic reactions, which leads to skin irritation.
Explanation:
The vesicles are the fluid-filled, small sacs, which can develop on the skin. The fluid within these sacs may be white, clear, or even mixed with blood. They are also sometimes considered as bullae or blisters. The development of vesicles takes place when the fluid gets occupied within the epidermis, that is, the skin's top layer.
Various health conditions can lead to the condition, however, the formation of vesicles is consistent with the allergic reactions that lead to skin irritation.
