Answer:
Option D, oxidized
Explanation:
The NADH gets oxidised when it passes its electrons into the Electron Transport System
Oxidization is a process in which one element or compound loses its electron to other chemical element or compound thereby itself getting oxidised and reducing the other one (the one who gains the electron). 
Here in the electron transport system, the NADH loses or donates its electron to the Electron Transport System thus chemically it gets oxidized.
Hence, option D is correct

<em>CORRECT STATEMENTS
> Water forms hydrogen bonds with other polar molecules. </em>
<em>> Water is a polar molecule. </em>
<em>> Water dissolves more ionic compounds.</em> 
<em />Water is a polar molecule because of its uneven distribution of electron density. It is made up of two hydrogen atoms and one positive atom. 
Since water is a polar molecule, it forms hydrogen bonds with other polar molecules. Though these bonds are relatively weak, however, there are so many of them present in water. 
Water also dissolves most ionic compounds due to the fact that water is a universal solvent. When these compounds are added to water, there will be an interaction between the individual ions and the polar regions of the water molecules and disrupts the ionic bonds. 
<em>INCORRECT </em>
> Liquid water is less dense than water vapor. - Liquid water has a higher density than water vapor. The fact that water vapor rises indicates that it is less dense than water.
>Water dissolves more hydrophobic substances. - Hydrophobic substances do not dissolve easily in water. It is termed as 'hydrophobic" because it means water-fearing. 
        
             
        
        
        
To relieve airway obstruction in infants, lay the baby face down along your forearm using your laps for support. Apply five quick, forceful blows at the baby's back with the palm of  your hand.
If the object did not come out, turn the baby face up and give five quick down thrusts. Continue the back slaps and the chest thrust cycle until the baby recovers.
