Let `n_1 and n_2` be the number of red and black balls respectively, in box I. Let `n_3 and n_4` be the number of red and black ball respctively, in box II.: One of the two boxes , box I andbox II, was selected at random and a ball was drawn randomly out of this box. The ball was found to be red.
If the probability that this red ball was drawn from box II is `1/3`,
then the correct option(s) with the possible values of `n_1, n_2, n_3 and n_4` is (are):

Options

A. `n_1=3, n_2=3, n_3=5, n_4=15`
B. `n_1=3, n_2=6, n_3=10, n_4=50`
C. `n_1=8, n_2=6, n_3=5, n_4=20`
D. `n_1=6, n_2=12, n_3=5, n_4=20`
