A mixture of hydrogen and oxygen would not need to have a certain ratio of hydrogen atoms to oxygen atoms to differ from the compound known as water.
<h3>Why is water a compound not a mixture?</h3>
A water molecule has 2 hydrogen atoms bonded chemically to oxygen atoms and has the formula H₂O.
In a chemical reaction, two atoms react together chemically to form a new product which means the reactants lose their individual properties and obtain new properties of the product formed.
Hence, water is a compound as hydrogen and oxygen atoms are bonded chemically to each other.
On the other hand, if oxygen and hydrogen form a mixture which is a physical change then they retain their individual properties in the mixture. They do not need to be in a specific ratio and there are no chemical changes taking place.
Chemical change determines if a substance is a mixture or a compound.
Thus, a mixture of hydrogen and oxygen is different from water if it doesn't have a certain ratio of hydrogen atoms to oxygen atoms.

The second option
Explanation:
Check
2×2Fe = 4Fe. Both sides have 4 Fe's
2x3 O = 3x2 O Both sides have 6 O's
3x1C = 3 C Both sides have 3 C's
