Answer:
(B) The world around you.
Explanation:
Science is an endeavor that does just that: asks questions about the world around us, and attempts to answer them, too. The questions it asks, when formulated precisely, are referred to as hypotheses (so the answer D is incorrect here). Scientists develop theories and observe natural laws (covered by choice C), design experiments and evaluate test results (choice A). But in the end, it is all about asking scientific questions about the world around you. The choice (B) is the best answer.
