Carlos is trying to determine how music affects the growth of bean plants. He hypothesizes that classical music will cause a pla

nt to grow at a higher rate than no music or rap music. He grows nine bean plants in similar lighting, temperature, and soil conditions. Three are exposed to classical music 24 hours a day, three are exposed to rap music 24 hours a day, and three are grown in complete silence.

A: A specific hypothesis predicting a relationship between independent and dependent variables
B: Controlled variables to ensure only the independent variable is being changed
C: Experimental data collected regularly that can be recorded and analyzed
