Which of the following reactions represents symbolic combination reaction?

Correct option is A

The correct answer is (A) A + B → C.

• A combination reaction (also called a synthesis reaction) is a type of chemical reaction where two or more reactants (A and B) combine to form a single product (C).
• The general symbolic representation of a combination reaction is: A+B→C
• This contrasts with:
• Decomposition reaction (e.g., XY→X+Y).
• Double displacement reaction (e.g., AB+CD→AC+BD).
• Single displacement reaction (e.g., PQ+R→PR+Q).
