Correct option is D
Given:
We are asked to form 3-digit numbers using the digits 0, 3, and 5,
without repeating any digit.
Concept:
A 3-digit number cannot start with 0.
We are to use all 3 digits exactly once in each number.
So we are calculating the number of 3-digit permutations of 0, 3, and 5 excluding those starting with 0.
Solution:
Total permutations of 3 digits without repetition = 3! = 6
List of all such numbers using 0, 3, 5:
035 (invalid – starts with 0)
053 (invalid – starts with 0)
305
350
503
530
Only 4 valid three-digit numbers.
Final Answer: 4
