None of the categories fit perfectly. However, given the options, "Technology & Programming" is the closest match, but it's not a precise fit as "Mantle-system" doesn't specifically denote a technology or programming-related term, assuming it refers to the Earth's mantle system in geology. Thus, selecting "Science & Research" as the most fitting category from the list provided.

Note: Based on the title "The Real Blackmarket", the most specific, relevant category is not clearly evident due to the ambiguity of the term "Blackmarket". However, it can be interpreted in a few ways.

The most fitting category might be "Other / Unclassified" as it doesn't fit neatly into any of the other categories.
