Option 1,2 and 3 will be positive irrespective of the value of S and P.
Option 4: that is p^2 - s^2 will be positive because |p| > s
For instance let p= -10 and s= 1
So p^2 - s^2= 100 -1 = 99, which is a positve number.
Now for option 5 :
If we use the same values, that is p= -10 and s = 1.
We get 1-100= - 99.
Hence option 5 is a negative number.
