What statement is true regarding the requirements for all traps?

The requirement that all traps must be numbered and tagged is crucial for several reasons. It ensures that traps can be easily identified for ownership, management, and regulatory purposes. Tagging traps helps wildlife officials monitor trapping practices and enforce regulations effectively, maintaining accountability among trappers. This requirement aids in preventing over-trapping and encourages responsible usage, as trappers must adhere to regulations concerning sizes, types, and the intended use of these devices.

While the other options might sound feasible in a general conservation context, they do not hold true as universal requirements specific to trapping. For instance, not all trapping regulations necessitate color-coding, seasonal registration, or mandate biodegradable materials, as these vary depending on specific local laws or practices rather than a blanket rule set by wildlife management authorities.
