ABC Company intends to implement a workflow that involves Saviynt User Group's approval.

To implement a workflow involving a Saviynt User Group's approval, the appropriate workflow block is B. TASK Access Approve. Here's an explanation:

Saviynt's Workflow Engine: Saviynt's workflow engine allows for the creation of complex approval processes using various building blocks or activities.

TASK Access Approve: This specific activity is designed to handle approval steps within a workflow. It allows you to define who the approver(s) should be and how the approval should be processed.

User Group Approval: To implement approval by a Saviynt User Group, you would configure the "TASK Access Approve" activity as follows:

Approver Type: You would select "User Group" as the approver type.

User Group Selection: You would then specify the particular Saviynt User Group that should be responsible for the approval.

Approval Logic: You can define whether all members of the group must approve, or if a certain number or percentage of approvals is sufficient.

Saviynt User Groups: User Groups in Saviynt are collections of users, often based on department, role, or other criteria. They are useful for managing access and approvals at a group level.

Other Options:

A. CONDITION IF Else: This block is used for branching logic in a workflow, not specifically for assigning approvals to user groups.

C. Action Prompt: This might be used for displaying information or collecting input, but not for defining an approval step.

D. TASK Custom Assignment: While you could potentially use custom assignment with scripting to achieve user group approval, the "TASK Access Approve" activity provides a more straightforward and built-in way to do it.

In conclusion: The "TASK Access Approve" workflow block in Saviynt, configured with a User Group as the approver type, is the most appropriate and direct way to implement a workflow that requires approval from a specific Saviynt User Group.
