Section 11.6, 'Embed the outcomes': The purpose of this process is stated as "to manage the transition of the capabilities delivered by the programme into business-as-usual (BAU) activities, and to ensure that the outcomes are embedded and benefits are realized." (p. 137). This directly supports the correct answer.
Section 11.5, 'Deliver the capabilities': The purpose is "to manage the delivery of the capabilities that are defined in the programme’s target operating model." (p. 133). This confirms it is about delivery, not post-delivery benefits focus.
Section 11.7, 'Close the programme': The purpose is "to provide a controlled and orderly end to the programme." It includes confirming "that a plan is in place for any post-programme activities, including benefits reviews." (p. 141). This shows it's about handover, not the embedding activity itself.
Section 11.4, 'Design the outcomes': This process includes 'Plan progressive delivery' and its purpose is "to design the future state of the organization... and to plan and design the programme." (p. 127). This confirms it is a planning process.
