Identify the correct combination of $A$, $B$, and $C$ involved in lactic acid fermentation.
$C_6H_{12}O_6 \rightarrow A + B \rightarrow$ Lactic acid + $C$

• A

  Option	$A, B, C$ Combination
  $A$	$A: 2 \ NADH + H^+, B: 2 \ NAD^+, C: \text{Pyruvic acid}$

• B

  Option	$A, B, C$ Combination
  $B$	$A: 2 \ NADH + H^+, B: \text{Pyruvic acid}, C: 2 \ NAD^+$

• C

  Option	$A, B, C$ Combination
  $C$	$A: \text{Pyruvic acid}, B: 2 \ NADH + H^+, C: 2 \ NAD^+$

• D

  Option	$A, B, C$ Combination
  $D$	$A: \text{Pyruvic acid}, B: 2 \ NAD^+, C: 2 \ NADH + H^+$
