Answers

GPT-4o mini
The correct methods of making wood packaging material (WPM) compliant typically include:

1. Heat treatment
2. Fumigation (often specifically with methyl bromide)
3. Dielectric heating (such as microwave treatment)

Given the options you provided, the closest correct set of methods is:

**Heat treatment, fumigation and dielectric heating**.

This combination is consistent with international standards for WPM, specifically ISPM 15, which outlines methods for treating wood packaging to ensure it is free from pests.
