Refer to the given letter, number and symbol string and answer the question that follows.

(Left) * 5 U £ $$\pm$$ 2 W @ 3 K 9 $$\div$$ # 6 M & 4 A $$\alpha$$ 5 G $$\delta$$ 7 B % R $$\varnothing$$ (Right)
If the sequence of the middle nine elements in the given string is reversed , then which of the following will be seventh to the right of the twenty-first element from the right end?

* 5 U £ $$\pm$$ 2 W @ 3 K 9 $$\div$$ # 6 M & 4 A $$\alpha$$ 5 G $$\delta$$ 7 B % R $$\varnothing$$

In this sequence 3 K 9 $$\div$$ # 6 M & 4 A $$\alpha$$ is the middle 9 terms.

If we reverse this we get $$\alpha$$ A 4 & M 6 #  $$\div$$ 9 K 3

* 5 U £ $$\pm$$ 2 W @ $$\alpha$$ A 4 & M 6 # $$\div$$ 9 K 3 5 G $$\delta$$ 7 B % R $$\varnothing$$

The twenty-first element from the right end will be W. Then seventh to the right of that W will be 6.
