Answer:

B. 10 th

Read Explanation:

After interchanging jijin's position from left is 6th as well as 18th from right (because before interchanging arya's position from right was 18th) then the total students =m+n-1 =18+6-1=23 After interchanging arya's postion from left is 14th so arya's position from the right is 23=14+n-1 24=14+n n=10
