Solution

The correct option is C 4
Using the digits, 6, 0 and 5, we can form 4 three digit numbers.
They are 650, 605, 560, 506.
Since a number cannot begin with the digit 0, the numbers, 065 and 056 are 65 and 56, which are two digit numbers.
Hence, only 4 three digit numbers can be formed using 6, 0 and 5
