A.

7

B.

4

C.

6

D.

2

Correct option is C

Given: 4173685
Add 1 to each odd digit and subtract 2 from each even digit.
4 is even → 4 - 2 = 2
1 is odd → 1 + 1 = 2
7 is odd → 7 + 1 = 8
3 is odd → 3 + 1 = 4
6 is even → 6 - 2 = 4
8 is even → 8 - 2 = 6
5 is odd → 5 + 1 = 6
The new number becomes: 2 2 8 4 4 6 6
So, the digits second from the right is: 6
Thus, correct option is (c).
