Answer:
The correct answer will be- If exposed to sunlight, plants grow faster than non exposed plants.
Step-by-step explanation:
A scientific hypothesis is a predicted idea proposed which explains the natural event to a limited extent. A hypothesis is based on the previous research work on the same issue, therefore, it is even considered an educated guess.
A hypothesis is designed in a way that it could be tested so it should contain all the variables a well as it could explain the possibility of the scientific question.
In the given question, the person noticed that plants grew faster in sunlight so the hypothesis will be- If exposed to sunlight, plants grow faster than non exposed plants. Here the growth of the plant will be the dependent variable while sunlight will be the independent variable.
