What is tru of a secular activity

It is separate from all religious traditions.

'It is compatible with all religious traditions' is true about secular activities.

Explanation:

Secularism is defined as the act of being compliant with all religions and their religious traditions. Thus, a secular activity would thereby imply that the activity being talked about in the question is also respectful of the various religions and religious traditions, without offending or leaving out any religion, or at the very least trying its best to. Thus, this makes the option compatible with all religious traditions the correct answer for this question. Other options doesn't follow the definition for secularism and hence are not an appropriate fit for the definition of a secular activity.
