①A prime number is a natural number greater than $$1$$ that has no other factors than $$1$$ and itself.  ②Decomposing a composite number into the product of several prime factors is called decomposing prime factors.  ③$$1$$ is neither a prime number nor a composite number. So $$\text{D}$$ is not correct.  The $$\text{A}$$ option is also incorrect. $$8$$ is not a prime number, so $$\text{C}$$ is incorrect. 
Which of the following prime factorization below is correct? 

  * $$97=1\times97$$ 
  * $$85=5\times 17$$ 
  * $$64=8\times 8$$ 
  * $$52=1\times 2\times 2\times 13$$
