Jia observes that adding a solution of sodium hydroxide to a clear liquid turns the liquid pink. She makes a hypothesis about why the liquid changed color.

C)ability to be proven incorrect

D)based on her current knowledge

B)based on the opinion of her classmates

Hypothesis is always based on empirical observation and not on popular opinion, hence the opinion of Jia's classmates is least important in Jia's formulation of a hypothesis.

so the answer would be radiation.
