Let us assume P = -1
That would reduce \(\frac{1}{P}\) to \(\frac{1}{-1}\) = \(-1\)
This would eliminate A,B and C
Now if P was -2 instead of -1 then \(\frac{1}{p}\) would be -0.5 which is greater than -1
Among option D and E ; D is the answer

TEST some values of p
If p = -1, then 1/p = 1/(-1) = -1
Check the answers:
A. \(\frac{1}{p}>-1\) NOT TRUE - ELIMINATE
B. \(\frac{1}{p}<-1\) NOT TRUE - ELIMINATE
C. \(\frac{1}{p}\neq{-1}\) NOT TRUE - ELIMINATE
D. \(\frac{1}{p}\geq{-1}\) TRUE - KEEP
E. \(\frac{1}{p}\leq{-1}\) TRUE - KEEP
Try a different value of p
If p = -2, then 1/p = 1/(-2) = -0.5
Check the REMAINING answers:
D. \(\frac{1}{p}\geq{-1}\) TRUE - KEEP
E. \(\frac{1}{p}\leq{-1}\) NOT TRUE - ELIMINATE
Answer: D
