3. Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2 H₂O represents a neutralization reaction.
<u>Explanation:</u>
Neutralization reaction is a reaction in which an acid reacts with a base to form a slat and water.
First reaction is the decomposition reaction in which the reactant is decomposed to form 2 or more products.
Second one is the combustion reaction in which methane is burnt in presence of oxygen.
Third one is the Neutralization reaction, in which calcium hydroxide (base) reacts with sulfuric acid (acid) to form a (salt) calcium sulfate and water.
Fourth reaction is nothing but the double displacement reaction in which the ions exchanged their positions there by forming two new products.

Explanation:
You need to give more explanation about it but if i understand a little abt what ur saying so i thinks it’s true
Answer:
<u>The half-reaction that occurs on the anode of an electrolytic cell is called oxidation.
</u>
This can easily be depicted by a chemical reaction as such <u>"Zn(s) = Zn2+ (aq) + (2e-)"
</u>
While, the Zinc in this reaction loses two elections. Hence copper gains those electrons and becomes solid.
<em>These reactions occurring on the anode are called positive reactions.
</em>
While the reaction that occurs on the cathode is called reduction. This reaction can be represented by this equation "<u>Cu2+ (aq) + 2e- = Cu(s)</u>".
<u>These non-spontaneous reactions occurring in an electrolytic cell together are called redox reactions. These generate electrical energy.</u>
I think B, don’t come at me if I’m wrong
