The graph gives the magnitude B(t) of a uniform magnetic field that exists throughout a conducting loop, perpendicular to the plane of the loop. Rank the five regions of the graph according to the magnitude of the emf induced in the loop, greatest first

• A.            b > (d = e) < (a = c)                   
• B.            b > (d = e) > (a = c)                                                                
• C.            b < d < e < c < a
• D.            b > (a = c) > (d = e)
