Solution
The correct options are
C Region A will be represented as a trough.
D Region B will be represented as a crest.
It can be noticed that the number of particles in region A is less than that of the region B. So, region A is a low pressure region (due to relatively fewer number of molecules) and B is a high pressure region (due to relatively higher number of molecules). Hence, region A will be marked by a trough and region B will be marked by a crest.
