(C) The original sequence is $8, 9, 0, 3, 2, 1, 4, 6, 7, 5$.There are $10$ digits in total.The interchange pattern is: $1^{st} \leftrightarrow 6^{th}$,$2^{nd} \leftrightarrow 7^{th}$,$3^{rd} \leftrightarrow 8^{th}$,$4^{th} \leftrightarrow 9^{th}$,$5^{th} \leftrightarrow 10^{th}$.Applying these interchanges:$1^{st}$ $(8)$ swaps with $6^{th}$ $(1)$ $\rightarrow$ $1, 9, 0, 3, 2, 8, 4, 6, 7, 5$$2^{nd}$ $(9)$ swaps with $7^{th}$ $(4)$ $\rightarrow$ $1, 4, 0, 3, 2, 8, 9, 6, 7, 5$$3^{rd}$ $(0)$ swaps with $8^{th}$ $(6)$ $\rightarrow$ $1, 4, 6, 3, 2, 8, 9, 0, 7, 5$$4^{th}$ $(3)$ swaps with $9^{th}$ $(7)$ $\rightarrow$ $1, 4, 6, 7, 2, 8, 9, 0, 3, 5$$5^{th}$ $(2)$ swaps with $10^{th}$ $(5)$ $\rightarrow$ $1, 4, 6, 7, 5, 8, 9, 0, 3, 2$The new sequence is $1, 4, 6, 7, 5, 8, 9, 0, 3, 2$.The seventh number from the right end is the $4^{th}$ number from the left end,which is $7$.

If the position of the first and the sixth digits of the sequence of numbers $8, 9, 0, 3, 2, 1, 4, 6, 7, 5$ are interchanged,the second and the seventh and so on,which number would be seventh from the right end?
