FlexConnect mode with local authentication and local switching. Answer D implies this since central switching implementation would result in an increase in traffic traversing between the APs and WLC.

Local authentication can only be enabled on the WLAN of a FlexConnect access point that is in local switching mode. Question says The senior management wants to utilize the wireless network for all the employees. I reckon than FlexConnect mode with OfficeExtend enabled is the best option to choose

this is a typical Cisco question that attempts to draw away attention from the critical and important aspects you should be considering. The statement: "wants to utilize the wireless network for all employees" is completely irrelevant in this context as there is no mention of location(office or home). This is a mere deflection, so OfficeExtend option would not be a best answer, since there's that possibility that the Wireless usage all the employees in reference might just be at the office locations ONLY.

OfficeExtend make sense on Internet, but these employees are connected through MPLS

As Guglielmino says would make sense if it say Internet instead of MPLS. Moreover, it says the corporation has spread over several countries hence it's a central WLC so it's RELEVANT to consider OfficeExtend as an option. Hence, I disagree with chomjosh argument but since the question mentions MPLS what Guglielmino said must be considered. OfficeExtend is not a suitable option here because of that.

This answer is completely irrelevant. The question is asking how to minimise traffic between the AP and controller which is located over the WAN. Answer would be FlexConnect for local switching and local authentication. Provided answer is correct.

OEAP allows the control of what traffic goes back to the WLC by deciding what traffic will be split tunneled.

I think the answer here should be C A Cisco OfficeExtend access point (Cisco OEAP) provides secure communications from a Cisco WLC to a Cisco AP at a remote location, seamlessly extending the corporate WLAN over the Internet to an employee’s residence. The user’s experience at the home office is exactly the same as it would be at the corporate office. Datagram Transport Layer Security (DTLS) encryption between the access point and the controller ensures that all communications have the highest level of security.Cisco OEAPs are designed to work behind a router or other gateway device that is using network address translation (NAT). NAT allows a device, such as a router, to act as an agent between the Internet (public) and a personal network (private), enabling an entire group of computers to be represented by a single IP address. There is no limit to the number of Cisco OEAPs that you can deploy behind a NAT device.

you said yourself : (...) over the Internet (...) but the question says through MPLS which normally is more expensive. Hence, Local Auth is a more suitable option. If the question would have mentioned Internet then OfficeExtend would have more sense IMO.
