a.can be several hundreds of kilometers in diameter.
b.begin as tropical disturbances off the east coast of South America.

Explanation / Answer
Hurricanes begin as a tropical storm of the Atlantic and Pacific ocean near the equator, and not in the east coast of South America. So the correct option is B.
Lightning occur when the top of the cloud is positively charged and cloud's base is negatively, but here it states cloud's base to be positively charged. So the correct option is B.
Prevailing winds are the result of the air being moved by the convection current, so it's not the base of convection cell, it is one of the result of convection cell. Here also the correct option is B.
