I would go with A

from I) k must be bigger than 1, otherwise would be negative

from II) k can be for instance -0.5 and 1/k+1 > 0 holds
also k can be 2 and 1/k+1 > 0 holds, therefore is insufficient

Anothyer one for A...

From A we get 1/(k-1)>0 or k-1>0 or K>1

From B we get -1<k<2!


Hence A survives!

1) 1/k-1 >0

2) 1/k+1 >0

is 1/k>0 => is k<0 i.e. is k -ve

from 1) if 1/k-1>0 => k-1<0 => k<1 so we can't say from this

from 2) 1/k+1 >0 => k+1<0 => k is -ve and < -1

Answer is B
