Explanation:

Question 9

Scientists form hypotheses by using observations to make testable predictions (not guessing, random explanations, or only quantitative data). Option d matches this.

A scientific observation is noticing/describing events objectively (not guessing, concluding without evidence, or interpreting subjectively). Option c is correct.

Qualitative data is non - numerical (like smell). Weighing, measuring speed, and counting are quantitative (numerical). So option a is correct.

Answer:

d. By using observations to make testable predictions
