Consider a program that computes the factorial of a number (n). From the specifications you know that:• If n < 0, a message "Value out of range" must be issued• If 0 ≤ n ≤ 100, the program calculates the factorial and returns the number• If 100 ≤ n ≤ 200 message "Value out of range" must be issuedWhich of the following statements about the equivalence partitions is CORRECT?

1. A. There are 3 partitions - one for negative numbers, one for numbers up to 100 and the last one for numbers up to 200
2. B. The requirements are not correct because the partitions are overlapping — đáp án hiện tại
3. C. The equivalence partitions cannot be determined for this question because the error message for two partitions is exactly same
4. D. The equivalence partitions cannot be determined for this question because factorial of numbers close to 200 will be very large
