Ans D

if [x] denotes largest integer less than or equal to x this means

if x = 2.5 then [x] = 2 (greatest interger condition is applicable...in fraction)

if x = 1 then [x] = 1 ( greatest and equal to condition applicalbe....in integer)

now apply this logic in reverse direction we get if [x] = -1 then x has to be greater than and equal to -1 but x cannot be = 0 becoz if it is = 0 then [x] = 0 thus

Ans is -1=<x<0...OA D
