Given below are two statements:
Statement I: $$H_2O_2$$ can act as both oxidising and reducing agent in basic medium.
Statement II: In the hydrogen economy, the energy is transmitted in the form of dihydrogen. In the light of the above statements, choose the correct answer from the options given below:

We need to evaluate both statements about $$H_2O_2$$ and the hydrogen economy.

Consider Statement I: $$H_2O_2$$ can act as both an oxidising and a reducing agent in basic medium. In $$H_2O_2$$, the oxidation state of oxygen is $$-1$$, which lies between $$0$$ (in $$O_2$$) and $$-2$$ (in $$H_2O$$ or $$OH^-$$). Because of this intermediate oxidation state, $$H_2O_2$$ can either gain electrons (be reduced, acting as an oxidising agent) or lose electrons (be oxidised, acting as a reducing agent). When acting as an oxidising agent in basic medium, oxygen goes from $$-1$$ to $$-2$$, for example: $$H_2O_2 + 2e^- \rightarrow 2OH^-$$. When acting as a reducing agent in basic medium, oxygen goes from $$-1$$ to $$0$$, for example: $$H_2O_2 + 2OH^- \rightarrow O_2 + 2H_2O + 2e^-$$. This is seen when $$H_2O_2$$ decolourises acidified $$KMnO_4$$ (reducing agent) or when it oxidises $$I^-$$ to $$I_2$$ (oxidising agent). Statement I is true.

Consider Statement II: In the hydrogen economy, energy is transmitted in the form of dihydrogen. The hydrogen economy refers to a system in which hydrogen gas ($$H_2$$, dihydrogen) is used as the primary energy carrier. Energy from various sources (solar, nuclear, etc.) is used to produce $$H_2$$ (for example, by electrolysis of water), and this $$H_2$$ is then stored, transported, and used in fuel cells or combustion to release energy where needed. Thus, dihydrogen serves as the medium through which energy is transmitted and distributed. Statement II is true.

Since both statements are true, the correct answer is Option (2): Both statement I and statement II are true.
