If a denotes a rational number, then the following statement is correct: a | a | must be a positive number; B - (- a) must be a positive number; C if - | a | must be a negative number D | a | must not be less than a

If a denotes a rational number, then the following statement is correct: a | a | must be a positive number; B - (- a) must be a positive number; C if - | a | must be a negative number D | a | must not be less than a

D | a | must not be less than a
Must not be less than A. is greater than or equal to a
So right
