An electron present in the third excited state of a H atom returns to the first excited state and then to the ground state. If $$\lambda_1$$ and $$\lambda_2$$ are the wavelengths of light emitted in these two transitions respectively, $$\lambda_1 \colon \lambda_2$$ is

A

$$4 \colon 1$$

B

$$5 \colon 9$$

C

$$3 \colon 1$$

D

$$2 \colon 1$$
