I really don't understand the logic behind OA as C unless what you are looking for is least possible value of |x| and not x.
Even the retired thread gives answer as C..
Now |x|<5-y, where y is a positive integer...
5-y will always be non-negative as we have |x| on other side..
But |x| can give x as both positive and negative, and is NOT given as an integer
For least possible value, we will take the max value of 5-y which is 5-1=4..
Now |x|<4, so possible value of x is 3.99, 3, 2, 1, 0.5, 1, -1, -2 , -3, -3.999..
Least value is -3.9999999..
