Note:  Among the three (3) answer choices given:  "-1" ;  "0" , and "50" ;  

 The numbers:  "0" and "50" are both considered "integers" and "whole numbers".  Note that "negative numbers" (that do not contain any fractions or decimals) — such as " -1 " —  are considered "integers" but NOT "whole numbers" .  

    →  As such, the remaining answer choice:  " -1 " ;

    →  which is:  "Answer choice:    [A]:   " -1 "  ;  is the correct answer.
