The figure shows four wire loops, with edge length of either `L` or `2L`. All four loops will move through a region of uniform magnetic field `vecB` (directed out of the page) at the same constant velocity . Rank the four loops according to the maximum magnitude of the e.m.f. induced as they move through the field, greatest first

A

`(e_(c)=e_(d)) lt (e_(a)=e_(b))`

B

`(e_(c)=e_(d)) gt (e_(a)=e_(b))`

C
