B2CD, DE3F, .... H5IJ, J6KL

1. D3GH
2. G3HI
3. FGH4
4. FG4H

Answer 1

Correct Answer - Option 3 : FGH4

Explanation :

We can see in the series B2CD, DE3F, .... H5IJ, J6KL that alphabets are in order

BCD then DEF then FGH then HIJ then JKL

and numerical are increasing and switching their position

2 then 3 then 4 then 5 then 6

So the series will  be B2CD, DE3F, FGH4 H5IJ, J6KL

Therefore option 3 is the right answer.
