Solution
The correct option is
B
All of above
In a synthesis reaction, two or more simple substances combine to form a more complex substance.
A decomposition reaction is when a more complex substance breaks down into its more simple parts.
It is thus the opposite of a synthesis reaction.
Displacement reactions can be a single displacement and double displacement.
Hence, the correct option is
D
