   Given inequality:

   • – 1 ≤ 3 – x < 4

   Simplify it as below.

   Add -3 to all sides:

   • – 1 – 3 ≤ – x < 4 – 3
   • -4 ≤ – x < 1

   Multiply all sides by – 1, it flips the inequality signs:

   • 4 ≥ x > – 1

   Show in reverse order:

   • – 1 < x ≤ 4 or
   • x ∈ (- 1, 4]

   Now verify the options.

   Correct choices are C, D, E, F, G.
