(B) The original number is $53216894$.There are $8$ digits in total. The rule is to interchange the $1^{st}$ with $5^{th}$,$2^{nd}$ with $6^{th}$,$3^{rd}$ with $7^{th}$,and $4^{th}$ with $8^{th}$ digits.Original positions: $1(5), 2(3), 3(2), 4(1), 5(6), 6(8), 7(9), 8(4)$.After interchanging:$1^{st}$ becomes $6$,$5^{th}$ becomes $5$.$2^{nd}$ becomes $8$,$6^{th}$ becomes $3$.$3^{rd}$ becomes $9$,$7^{th}$ becomes $2$.$4^{th}$ becomes $4$,$8^{th}$ becomes $1$.The new number is $68945321$.The digits from the right end are $1, 2, 3, 5, 4, 9, 8, 6$.The second digit from the right end is $2$.

The positions of the first and the fifth digits in the number $53216894$ are interchanged. Similarly,the positions of the second and the sixth digits are interchanged,and so on. Which of the following will be the second from the right end after the rearrangement?
