C. A strong current of warm water

Explanation:

A gulf stream can be defined as oceanic current which brings warm water from  Gulf of Mexico to the Atlantic ocean. This water current brings changes in the climatic conditions of the east coast of Florida, causing the temperatures warmer in winters and cooler in summers. The gulf stream also reaches some parts of European waters, this makes the atmosphere of the European countries warm.
