B does not align with AgilePM’s MoSCoW prioritization.

In AgilePM, Must Have requirements are the ones that are absolutely essential. If a Must Have is missing, the solution is not viable because it may be unusable, unsafe, non-compliant, or fail to deliver its core purpose.

A Should Have requirement is important, but it is not mandatory for the increment to be considered successful . It adds significant value, and the team aims to deliver it if reasonably possible, but the solution can still be successful without every Should Have being included.

Why the other options align:

A is correct because it accurately describes a Must Have.

C is correct because Could Haves are desirable but only delivered if time and capacity permit.

D is correct because Won’t Have this time items are deliberately excluded from the current increment and may be revisited later.

AgilePM perspective:

MoSCoW is used to protect delivery confidence and business clarity. It helps teams and stakeholders distinguish between:

what is essential,

what is important,

what is desirable,

and what is deferred.

The error in B is that it treats Should Have as if it were equivalent to Must Have , which is not how AgilePM defines the category.

So the correct answer is B .
