HELPPPPPPP ASAP PLEASEEEE

we know that
1) A conditional statement consists of two parts, a hypothesis and a conclusion 
2) To form the converse of the conditional statement, interchange the hypothesis and the conclusion
3) To form the inverse of the conditional statement, take the negation of both the hypothesis and the conclusion

therefore
if the converse is
If the sum of the exterior angles is 360 then the figure is a polygon

to find the inverse take the negation of both the hypothesis and the conclusion
so
the inverse is
If the sum of the exterior angles is not 360 then the figure is nor a polygon

the answer is the option B
If the sum of the exterior angles is not 360 then the figure is nor a polygon,
