`H_2 C_2 O_4` and `NaHC_2 O_4` behave as.acids as well as reducing agents. Which are correct statements?

Options

A. Equivalent weight of `H_2 C_2 O4` and `NaHC_2 O_4` are equal to their moleculear weights when acting as reducing agents.
B. Equivalent weight of `H_2C_2 O_4` and `NaHC_2 O_4` are equal to half their molecular weights when acting as reducing agents ,
C. 100 mL of 1 M solution of each is neutralized by equal volumes of `1 N Ba(OH)_2`
D. 100 mL of 1 M solution of each is oxidized by equal volumes of `1 M KMnO_4`
