The expression $$x[n]y$$ is defined for positive values of $$x$$ and $$y$$ and for positive integer values of $$n$$ as follows:

$$x[1]y = x^y,$$
If $$n$$ is odd, $$x[n+1]y = (x[n]y)^x,$$
If $$n$$ is even, $$x[n+1]y = (x[n]y)^y.$$

If $$y = \dfrac12$$ and $$x[4]y = 2,$$ then $$x =$$

A. $$\dfrac14$$

B. $$\dfrac12$$

C. $$1$$

D. $$2$$

E. $$4$$
