Answer: The correct answer is option (A).

Explanation:

Oxidation : A chemical reaction in which addition of oxygen occurs or removal of hydrogen occurs is called oxidation.

Reduction:A chemical reaction in which elimination of oxygen occurs or addition of hydrogen occurs is called reduction.

In a given reaction,:

[tex]C_6H_{12}O_6+6O_2\rightarrow 6CO_2+6H_2O+Energy[/tex]

The glucose molecule is getting oxidized into carbon-dioxide. Before oxidation in glucose molecule ratio of carbon and oxygen atom was 1:1 which changes to 1:2 after oxidation of glucose into carbon-dioxide.

Hence, [tex]C_6H_{12}O_6[/tex] is getting oxidized.

The oxygen molecule is reduced because addition of hydrogen atoms are taking place in oxygen molecules which gives water after reduction.

Hence, [tex]O_2[/tex] is getting reduced.

So, correct answer is option (A).

The statement that best described the results of the reaction is that C6H12O6 is oxidized and O2 is reduced.

Recall the definitions of oxidation:

addition of oxygen
removal of hydrogen
increase in oxidation number
loss of electrons

In this case, O2 which is essentially oxygen is added to C6H12O6. This agrees with the definition of oxidation as the addition of oxygen. Thus, C6H12O6 is said to be oxidized.

Any substance that oxidizes another substance usually gets reduced in reaction. Thus, the O2 is said to be reduced.
