Technology & Programming because the title "TONG KHU SALE MOC BAI CAMBODIA" likely refers to the name of a chat group or community about a project or development about a building named Baing Hin or other areas in Cambodia . The keywords here, "TONG KHU", translate TO HOUSE OR BUILD, imply an architectural or construction theme pointing toward the technology and programming category in this case. Given this context its more suitable to list it under the "Technology & programming" category but this may not be the best fit is there any more specific category in this list (not the case here) i will then recommend this.

Software development and growth of Cryptocurrency technologies. Therefore, the category name is: Blockchain & Web3

These conversations appear to be related to WordPress Development and SEO. However, the only relevant categories from the list are: Technology & Programming And since the subcategory is not available in the list, we can rescoop it as - WordPress falls under Technology & Programming category

Blockchain UNN is a community of Digital Enthusiasts with a drive to educate, impact and develop members of the University Community with basic knowledge of cryptocurrency and blockchain education, as well as development in UNN/UNEC Campuses.

Development / Tech was not in the list, though so I am going to say Technology & Programming

Development & Product Design

Software Development, Makers, and Tech Communities

Software Development

Web Development / Technology & Programming

Software Development

Mobile app development, Cloud computing, Cloud storage, Big data, cybersecurity, software are all part of Technology So the closest category would be: Technology & Programming

Web development or Technology & Programming appears to be the most suitable category since the entity name is DigiLOOM (a type of loom used for digital crafting, most likely a digital platform related to web or digital applications).
