Answer:
A. The ratio of the element in glucose is different than in ethanol
Explanation:
The compounds given are; 
       Glucose      C₆H₁₂O₆ 
      Ethanol         C₂H₆O 
The two compounds given are different from one another. But they have the same elemental composition. 
    Ethanol is made up of Carbon, hydrogen and Oxygen and so also, Glucose
Now, 
   The number of atoms in both compounds are different; 
                                    Number of atoms
                         C                             H                     O
Glucose           6                             12                      6
Ethanol            2                              6                       1
 
        
             
        
        
        
The molecules vibrate faster and space between atoms increase
        
                    
             
        
        
        
The complete statement will be "Support gases system are subject to the same hazards as, present in any piped medical gas system with the additional hazard of higher pressure"
<h3>What are gas systems?</h3>
Generally, A gas system is simply defined as an assemblage of tubes, used for gas reticulation and circulation.
In conclusion, a higher pressure will be experienced as an additional hazard to the medical gas system.
