Solution:
Though the lines look like lines in a rectangular coordinate system, it is possible they are not 90 degrees. But we know for sure, that these are straight lines which are vertically opposite, thus, their angles will also be same.
Therefore a+b=d+e, similarly, c=f. However, we cannot be sure that c=d+e or c=a+b
IMO C
Hope this helps!
