PLEASE HELLLPP ILL GIVE AND HEART how does the Gulf stream affect the east coast of the United States?

A ) The Gulf Stream carries cool water along the east coast, causing average temperatures to be cooler than they would be without the current.
B ) The Gulf Stream carries warm water along the east coast, causing average temperatures to be warmer than they would be without the current.
C ) The Gulf Stream carries water along the east coast but the average temperatures are not affected by the current.
D ) The Gulf Stream carries warm water along the east coast but the average temperatures are not affected by the current.
