Agree that it is C.

But

**Quote:**

I believe you have misunderstood St. (2).

'The largest negative element of set S is -1' implies that there can be no integer in set S which has a greater negative value than -1.

Also, we know that -1 is the first negative integer and thereby also the smallest negative integer.

I think the wording may be a little unclear in srihari's reply.

-1 is not the smallest negative integer- it is the highest of all negative integers as -1>-2>-3>-4>....

So the set can contain -8, -189 etc but it definitely contains -1. So i

So if the set has half positive integers (St 1) and has -1, it will look like (assuming 4 elements)

{-8,-1,1,2} - median is 0 - not negative

{-1,0,2,1} - median is 1 - not negative

The median will be the average of a positive integer and zero, or the average of a positive integer and a negative integer. Since -1 is the largest negative integer in the set, the median is either the average of a positive integer and zero, or the average of a positive integer and -1 - in both cases it can't be negative.
