She sets up three tanks with water at different pH levels: Tank A has a pH of 5, Tank B has a pH of 7, and Tank C has a pH of 9. She ensures that all tanks receive the same amount of light, the same type of algae, and the same temperature.

Which of the following is the best hypothesis for the algae experiment?

Options

"Algae will grow equally well at all pH levels."

"The growth of algae will be greatest at a pH of 7."

"Algae cannot grow in water with a pH higher than 9."

"The pH level will not affect the temperature of the water."
