The figure below shows transitions between three states of a molecule (labeled $E_1$, $E_2$, and $E_3$) that are observed through the emission and absorption of photons in a pair of experiments, A and B.
A
B
$E_3$
a
b
$E_2$
c
d
$E_1$
e
Which transitions are associated with the shortest-wavelength photon emission and longest wavelength photon absorption?
A. c and e
B. b and d
C. c and d
D. b and e
E. Can't tell without knowing the values of $E_1$, $E_2$, and $E_3$.
