What is the most safest type of trading?

Excuse me, could you please clarify something for me? I've been hearing a lot about different types of trading in the financial markets, and I'm trying to understand which one is considered the most safest. Is there a particular type of trading that stands out as being more secure or less risky than others? I'm looking for some guidance on this matter as I'm new to investing and want to make sure I'm making informed decisions. Could you enlighten me on this topic?
