The sentence with correct usage is:
A. The criteria for winning are strict.
Additionally, D. The media were present at the event. is also correct, as "media" is considered a plural noun in this context.
Options B and C contain errors:
- B should use "The data are consistent with our results." (because "data" is plural in a scientific context).
- C should use "The phenomenon was observed worldwide." (because "phenomenon" is singular).
