We are given that x is not equal to 0, so lets try x = 2 or -2,
A. 1/x<x ---> x = -2 ---> -0.5 < -2 , not true --> reject
B. −x<x ----> x = -2 ----> 2 < -2, not true --> reject
C. x^3 < x^5 ---> x = -2 ----> -8 < -32, not true --> reject
D. x<x^2+2 -----> x = -2 ---> -2 < 6, true. Lets try x = 2 as well -----> 2 < 6. Correct
E. −|x|<|x| ----> x = -2 ----> -2 < 2, true. Lets try x = 2, ---> -2 < 2. Correct
Hence options D and E are correct options and ans
A. 1/x<x ---> x = -2 ---> -0.5 < -2 , not true --> reject
B. −x<x ----> x = -2 ----> 2 < -2, not true --> reject
C. x^3 < x^5 ---> x = -2 ----> -8 < -32, not true --> reject
D. x<x^2+2 -----> x = -2 ---> -2 < 6, true. Lets try x = 2 as well -----> 2 < 6. Correct
E. −|x|<|x| ----> x = -2 ----> -2 < 2, true. Lets try x = 2, ---> -2 < 2. Correct
Hence options D and E are correct options and ans
