Number greater than 1000 but less than 4000 is formed using the digits 0, 2, 3, 4 when repetition allowed is

- 105
- 125
- 128
- 625

**Answer**

Let number of digits formed x.

1000 < x < 4000, which means left extreme digit will be either 2 or 3.

Required numbers = ^{2}C_{1} × HTU

where H = Hundred's place, T = Ten’s place, and U = Unit's place

= ^{2}C_{1} x 4 x 4 x 4 = 128

**The correct option is C.**
