Here is an idea of where I am :

Now,since I can't chose (1,2,3,5) and (1,2,8) together I need K disjoint subsets which I have been thinking on how to get.I initially thought of storing all the pairs in a double dimensional array and then bruteforcing random K subsets if it works out.But I thought I won't be able to pass within the given time limit so I didn't apply this logic. This situation is similar to the problem Exact Cover which is NP Complete I guess.
Also,keep DP as far away as possible from the solution because don't know it much.
