Answer:
B. Multi-cell line
Explanation:
A multi-cell line, or how it is more commonly known, a squall line, is basically a group of storms forming a line, like a bow, they have been seen to cover hundreds of miles long but usually only 10 or 20 miles wide.
It is theorized that this is because when a cyclone is formed, there are two forces of "wind" one ahead and one behind, concentrating air masses as if the winds were "squishing" them to form a line.
