$(1)$ Denaturation of proteins causes loss of secondary and tertiary structures of the protein.
$(2)$ Denaturation leads to the conversion of double strand of $DNA$ into single strand.
$(3)$ Denaturation affects primary structure which gets distorted.
$2NO(g) + 2{H_2}(g) \to {N_2}(g) + 2{H_2}O(g)$ is :
Step $1$ : $2NO(g) + {H_2}(g)\xrightarrow{{slow}}{N_2} + {H_2}{O_2}$
Step : $2$ ${H_2}{O_2} + {H_2}\xrightarrow{{fast}}2{H_2}O$
Then the correct statement is
$A.$ $\left[ Fe ( CN )_6\right]^{3-}$;$B.$ $\left[ FeF _6\right]^{3-}$; $C.$ $\left[ CoF _6\right]^{3-}$; $D.$ $\left[ Cr (\text { oxalate })_3\right]^{3-}$; $E.$ $\left[ Ni ( CO )_4\right]$
Choose the correct answer from the options given below:
$\begin{array}{*{20}{c}}
