$A$ particle starts at the origin and moves $1$ unit horizontally to the right and reaches $P_{1}$,then it moves $\frac{1}{2}$ unit vertically up and reaches $P_{2}$,then it moves $\frac{1}{4}$ unit horizontally to the right and reaches $P_{3}$,then it moves $\frac{1}{8}$ unit vertically down and reaches $P_{4}$,then it moves $\frac{1}{16}$ unit horizontally to the right and reaches $P_{5}$ and so on. Let $P_{n} = (x_{n}, y_{n})$ and $\lim_{n \rightarrow \infty} x_{n} = \alpha$ and $\lim_{n \rightarrow \infty} y_{n} = \beta$. Then,$(\alpha, \beta)$ is

• A
  $(2, 3)$
• B
  $(\frac{4}{3}, \frac{2}{5})$
• C
  $(\frac{2}{5}, 1)$
• D
  $(\frac{4}{3}, 3)$
