C is the intended answer in the legacy SMC question bank, but the wording is technically defective because of the word "only." Older SMC practice material keys C because SBOK historically described approximately 6-
10 members as the ideal Scrum Team size. The intended concept is therefore that a typical individual Scrum Team should remain relatively small.
However, this must not be interpreted to mean Scrum itself can only be used when an entire project contains
6-10 people. Current SCRUMstudy guidance explicitly states that Scrum can be applied to projects of any size or complexity and can scale to large projects containing many Scrum Teams.
Options A, B, and D are clearly false: Scrum is not restricted to small projects, software development, or large corporations.
Thus, for the historical SMC item, C is the expected exam answer, but the accurate SBOK interpretation is: a Scrum Team is ideally small; Scrum as a framework is not limited to projects having only 6-10 total participants.
