If no improvement is required, choose the option accordingly. World Health Day is celebrated to create consciousness about keeping healthy and conceal the information at all levels.

The sentence discusses: → World Health Day, → spreading awareness about health. Thus, the highlighted phrase should express: → spreading or communicating information publicly. “Conceal the information” is contextually incorrect because: “conceal” means hide, whereas awareness campaigns aim to spread information. “Disseminate the message” means: → spread the message widely, which perfectly suits the context.
