{'electropositive element increases': [0, 0, 0, 1], 'oxidation': [0, 0, 1, 0], 'electropositive clement': [0, 0, 0, 1], 'hydrogen': [0, 0, 1, 3], 'substance': [2, 1, 7, 7], 'proportion': [1, 1, 2, 8]}

The correct answer is option-1, which states that only statement 1 is true for oxidation. Let`s dissect both options to understand why.

Option-1 states that hydrogen is displaced from a substance during oxidation. This statement is correct because oxidation involves the loss of electrons, and hydrogen can lose its electrons and be displaced in certain reactions.

Option-2 states that an electropositive element is added to a substance, or the proportion of an electropositive element increases during oxidation. This statement is not necessarily true. While it is possible for an electropositive element to be involved in certain oxidation reactions, it is not a defining characteristic of oxidation. Oxidation can occur without the addition or increase of an electropositive element.

Therefore, option-1 is the correct answer. It accurately describes the displacement of hydrogen during oxidation. It is important to understand that oxidation can involve other elements and reactions as well, but the provided answer best captures the essence of oxidation in relation to hydrogen displacement.
