I think the answer is Self confidence
Were you asking what this means in English??
I used google translate and this is what it translated to: <span>What are science-based knowledge</span>
The answer is (a) because compro is bought in Spanish and in the question it says “yesterday he bought the gifts for his mother” so bought would be the best answer. (B) is to buy I guess like I will buy chicken. And (c) is like they bought chicken. How I know this is well I speak Spanish I hope this helps!
