A REST service uses XML as the serialisation format for all the resource representations exchanged with the server. Select which of the following reasons would be valid for using json instead. Select one:

a. Both would be suitable options, but json has convenient library support for de/serialising objects.

b. XML is binary coded, so it is unreadable by humans

c. XML is less efficient to process than json

d. Unlike XML, json provides us with schema functionality that automatically verifies the format of every resource.
