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 one red and b of red and black balls, respectively, in box II. A ball is drawn at random from box 1 and transferred to box II. If the probability of drawing a red ball from box I, after this transfer, is `1/3` then the correct option(s) with the possible values of `n_1 and n_2` , is(are)

A

`n_1=4 and n_2=6`

B

`n_1=2 and n_2=3`

C

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 one red and b of red and black balls, respectively, in box II. One of the two boxes, box I and box II, was selected at random and a ball was drawn randomly out of this box. The ball was found to be red. If the probablity 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)
