The answer is c.
hope this helps! :)
Answer: A. AB + C → AC + B
Explanation:
A single displacement reaction is also known as single replacement reaction. A reaction in which an element replaces another element from the compound is known as single displacement reaction.
AB + C → AC + B
Here, element C replaces another element B from compound AB.
Thus, option A represents is a general equation for a single displacement reaction
Option B represents a double displacement reaction where one element of a compound replaces another element of another compound and vice-versa, option C is a synthesis reaction where two reactants or more combine to form one product. Option D is a decomposition reaction in which multiple products are formed from a single reactant.
