Which question tests the relationship between light and germination?

Answer and explanation

Correct answer: Do seeds kept in light germinate faster than seeds kept in darkness?

Option A changes the light condition and compares the rate of germination, so it tests the relationship between light and germination. Options B, C, and D test the effects of water, seed size, and temperature respectively, not light. Exam tip: In a fair test, change only one factor at a time.
