35. Which of the following is a correct prediction of the chemical shifts (ppm) for the signals in the 1
H NMR spectrum for the
following compound? 
(A) a = 5.7, b = 5.2, c = 4.4, d = 1.9
(B) a = 5.2, b = 5.7, c = 1.9, d = 4.4
(C) a = 4.4, b = 5.2, c = 1.9, d = 1.9
(D) a = 5.2, b = 4.4, c = 5.7, d = 1.9
(E) a = 1.9, b = 5.7, c = 5.2, d = 4.4
(A) a = 5.7, b = 5.2, c = 4.4, d = 1.9
(B) a = 5.2, b = 5.7, c = 1.9, d = 4.4
(C) a = 4.4, b = 5.2, c = 1.9, d = 1.9
(D) a = 5.2, b = 4.4, c = 5.7, d = 1.9
(E) a = 1.9, b = 5.7, c = 5.2, d = 4.4
