Concept: A rational number's additive inverse is its inverse. The additive number and sum of a rational number are both zero.
It is the additive inverse of x when y equals x and has the opposite sign to x, and vice versa.
Inverse additive of 28 is
-(28)  = -28
Observing that 28+ (- 28) = 0
Inverse additive of -6-5.is
-(-6-5) = -65
Observing that -6-5 +(-65) = 0
So, the correct answer is -28 and -65.
Hence, the correct option is 1.
