Solution

The strength of cohesion from best to worst is generally:

Functional Cohesion

Sequential Cohesion

Communication Cohesion

Procedural Cohesion

Temporal Cohesion

Logical Cohesion

Coincidental Cohesion

Here, Functional Cohesion and Coincidental Cohesion are not given.

So, from the given options, best to worst order is:

Sequential Cohesion $\rightarrow$ Communication Cohesion $\rightarrow$ Procedural Cohesion $\rightarrow$ Temporal Cohesion $\rightarrow$ Logical Cohesion

According to given symbols:

$B\rightarrow C\rightarrow E\rightarrow D\rightarrow A$
