		for(int x= 1; x <= n; x++)
		  if(n%x == 0)
		    System.out.print(x+" ");

Answer: A

Explanation:

Class and Main Method:
- The class MCQ contains the main method, which is the entry point for the program.
- Inside the main method, an instance of MCQ is created, and the test method is called with the argument 12.
Method test:
- The test method takes an integer n as a parameter.
- It iterates through numbers from 1 to n (inclusive) using a for loop.
- Inside the loop, it checks if n is divisible by x using the condition if (n % x == 0).
- If the condition is true, it prints the value of x followed by a space.
Output Calculation:
- The test method is called with n = 12.
- The loop iterates from 1 to 12 and checks for divisibility.
- The numbers that divide 12 without leaving a remainder (i.e., the factors of 12) are 1, 2, 3, 4, 6, and 12.

Iteration	`x` Value	Condition `x <= n`	Condition `n % x == 0`	Action
1	1	true	true	Print `1`
2	2	true	true	Print `2`
3	3	true	true	Print `3`
4	4	true	true	Print `4`
5	5	true	false	Do nothing
6	6	true	true	Print `6`
7	7	true	false	Do nothing
8	8	true	false	Do nothing
9	9	true	false	Do nothing
10	10	true	false	Do nothing
11	11	true	false	Do nothing
12	12	true	true	Print `12`
13	13	false	-	Loop ends
