Best answer
Correct Answer - Option 1 : 9

Number: 341285769

1) If the positions of the first and the sixth digits of the number are interchanged;

3 4 1 2 8 5 7 6 9

341285769

New number = 541283769

2) the second and the seventh digits are interchanged;

5 4 1 2 8 3 7 6 9

Number = 571283469

3) the third and eighth digits are interchanged:

5 7 1 2 8 3 4 6 9

Number = 576283419

4) the fourth and ninth digits are interchanged

5 7 6 2 8 3 4 1 9

Number = 576983412

7th digit from the left end = 4

3rd to the left of the 7th digit from the left end = 9

Hence, "9" is the correct answer.
