The programme is in Tranche 2 and has been progressing according to plan.

Comprehensive and Detailed 200 to 250 words of Explanation From Exact Extract of project-programme-and-portfolio-management of 5th Edition MSP:

In MSP 5th Edition, the Structure Theme is heavily reliant on the principle of 'Realize measurable benefits.' A core tenet of this principle is that benefits should not be "big bang" deliveries at the very end of a programme. Instead, MSP advocates for an incremental approach where the programme is broken down into tranches, each culminating in a landing point. A landing point is a point in time when a set of capabilities is transitioned into the business, allowing for the realization of intermediate benefits and the embedding of new ways of working.

The SRO’s request to delay all transitions until the end of the programme directly contradicts this principle. Option C is correct because MSP 5th Edition mandates that outcomes of benefit should be embedded at these intermediate landing points. By doing so, the programme provides early value to the organization, validates the "pathway to benefits," and reduces the overall risk of failure. Delaying all transitions to the end creates a high-risk environment where the business may be overwhelmed by a massive amount of change at once. Furthermore, the feedback loop from Tranche 1 (the customer complaints) should be used to improve the transition process for subsequent tranches, not to abandon the incremental delivery model altogether. The structure of a programme is specifically designed to provide these "safe harbors" where progress is assessed and benefits are consolidated before moving forward.
