1 neither

O_{2}

is used, nor

{CO}_{2}

is liberated.

is liberated

3

O_{2}

is used,

is liberated

4

O_{2}

is used,

{CO}_{2}

is not liberated

Explanation:

During lactic acid fermentation, neither $O_{2}$ is used, nor ${CO}_{2}$ is liberated. During lactic acid fermentation in cell the pyruvate produced during glycolysis is converted to lactic acid by oxidizing an electron carrier.
