Computer Science/Professional: could potentially include more broad related disciplines such as programming and IT (done synonymous) wellbeing could be computing &computer science

I'm unable to determine any category from the given list directly fitting the description "CVD 3D". However, it appears to be related to "Technology", "AI", or "Machine Learning" (as in, computer vision or deep learning related technologies); specifically Computer-Vision or Deep-learning and three-dimensional. Since those aren't precise categories from this list there could be a few possibilities involving different combinations of the given categories: Technology & Programming AI & Machine Learning

I couldn't find a suitable category, but "Education & Learning" seems close. However, since "Education & Learning" is not the most specific category for the attributed name "RKD College Group", I would suggest categorizing this as "Education & Learning".

Philosophy and ethics ( closest fit would be under "Other / Unclassified"

Business & Finance & Law & Ethics

Ethical Hacking & Cybersecurity Note: Adversarial means (actions that are designed to test or attack an opponent's defence) usually means hacking or ethics because a large part of being adversarial tends to be tech-related

Tech ethics - suggest 'Ethical Hacking & Cybersecurity.'
