If all tasks must be executed in the same time-span, what type of cohesion is being exhibited?Select one:a.Functional Cohesionb.Temporal Cohesionc.Functional Cohesiond.Sequential Cohesion

The question asks about the type of cohesion exhibited when all tasks must be executed in the same time-span. Let's analyze the options step by step:

a. Functional Cohesion: This type of cohesion occurs when all parts of a module are grouped because they all contribute to a single, well-defined task. It is the highest level of cohesion and is not specifically related to the timing of tasks.

b. Temporal Cohesion: This type of cohesion occurs when tasks are related by the time they need to be executed. If all tasks must be executed in the same time-span, they are grouped together because of their timing, which is the defining characteristic of temporal cohesion.

c. Functional Cohesion: This option is a repeat of option a and can be disregarded as it does not provide new information.

d. Sequential Cohesion: This type of cohesion occurs when tasks are grouped because the output from one part of the module serves as input to another part. It is related to the order of execution rather than the timing.

Given the definitions, the correct answer is:

b. Temporal Cohesion

This is because temporal cohesion specifically refers to tasks that are related by the time they need to be executed, which matches the condition described in the question.
