\\text{MMR} = \\frac{\\text{Number of maternal deaths}}{\\text{Number of live births}} \\times 100{,}000

- An oxidizing agent is itself reduced. In option A, the oxidation state of Oxygen in $H_{2}O_{2}$ changes from $-1$ to $-2$ (in $H_{2}O$).
- Since the oxidation state decreases, $H_{2}O_{2}$ is reduced, meaning it acted as an oxidizing agent for the Iodide ions ($I^{-}$ to $I_{2}$).
Which lipids do NOT contain fatty acids?
