It seems like "BAS TERA SHAYAR" is a poem or a quote. However, I'll do my best to provide a suitable category from the list. Based on the poetic structure, I would categorize this as "Other / Unclassified" since it doesn't fit into any specific category like Technology or Gaming.

This title doesn't appear to be a specific, broadly recognized category. Since it doesn't fit into any of the provided categories well, I would choose: Other / Unclassified

Truth Theory is not explicit in its category, but based on the general context, it seems to fall under: Philosophy, Ethics and or general information could be suitable, but can't be found on the list, the most suitable match would then be: Spirituality & Religion
