Obviously, the correct answer is (c), synthesis reaction.

#### Explanation:

In a synthesis reaction, two or more chemicals are combined to form a new chemical compound.

For example, when we blow a spark in a vessel containing hydrogen and oxygen, both gases combine with each other to form water:

$2 {H}_{2} + {O}_{2} \rightarrow 2 {H}_{2} O$

Another typical case would be the formation reaction of ammonium chloride from hydrogen chloride and ammonia:

$H C l + N {H}_{3} \rightarrow N {H}_{4} C l$.
