ANSWER: B

Using the formula, sum of interior angles for a polygon with n sides = (n-2)*180
here, the number of sides, n=7
a+b+c+d+e+f+g = (7-2)*180 = 900

900<1080

Another approach

We can visually solve this. Just connect all the vertices from any specific vertex. Then we'll get 4 edges which make 5 sections. Thus 5*180 = 900

Quant B greater.
