ANSWER


The set of all rational numbers and the set of all real numbers.


EXPLANATION

The set of rational numbers contains all numbers that can be written in the form,



`(a)/(b)`


where a and b are integers and b≠0.


The given number is


`- (1)/(2)`


It belongs to the set of rational numbers.


The set of rational numbers is a subset of the set of real numbers.

Hence


`- (1)/(2)`
also belongs to the set of real numbers.


The correct answer is A.
