If X follows the normal distribution with mean $$\mu$$ and variance $$\sigma^{2}$$, the fourth moment about origin is:

A

$$\mu^{4} + 4\mu^{2}\sigma^{2} + 4\sigma^{4}$$

B

$$3 \mu^{4} + 4\mu^{2}\sigma^{2} + 3\sigma^{4}$$

C

$$\mu^{4} + 6\mu^{2}\sigma^{2} + 3\sigma^{4}$$

D

$$\mu^{4} + 4\mu^{2}\sigma^{2} + 3\sigma^{4}$$
