Which term means basic or fundamental in nature?

• A. Basal
• B. Misteryo ng buhay
• C. Pagsalungat
• D. Pag-uulit

Answer: (A)

Basal means being at the base or foundation—the most basic, underlying level of something. It’s the word you’d use when you want to describe something that forms the starting point or essential base of a system. For example, in biology and everyday science, basal layers or basal processes refer to the foundational, bottom-most aspects from which other features develop. That sense of base or starting point lines up with “basic or fundamental in nature.”

Misteryo ng buhay points to life’s mysteries, not to a base or foundation. Pagsalungat means opposition or resistance, and Pag-uulit means repetition. None of these convey the idea of being foundational, which is why they don’t fit.
