Choose the correct answer from the options given below:

Solution

✅ Correct Option: 4

A: −1<x−3<1-1<x-3<1 gives (2,4)(2,4) (IV).

B: −5<3−5x<5-5<3-5x<5 gives −25<x<85-\dfrac{2}{5}<x<\dfrac{8}{5} (I).

C: a number is less than its modulus only when it is negative, so 2x+1<02x+1<0, giving x<−12x<-\dfrac{1}{2} (II).

D: −8<7−3x<8-8<7-3x<8 gives −13<x<5-\dfrac{1}{3}<x<5 (III).
