If R is between (2) and (-2), which of the following can be greatest?
Kindly check that the OA is correct As A can't be the correct answer. By the way, Quality of the question is very poor because the different options can lead to different answers.
If R = -1 ,
1/R = -1
R^2 = 1, Thus A can't be the right answer.
The best answer among the options is B.
Hope this explanation helps.
