<span>The independent variable is the one that researchers directly change. Here, the students will deliberately change the temperature, so the independent variable will be temperature in degrees. The dependent variable is the one that researchers measure as the outcome of the experiment. Here, the students will measure the time it takes until the water is gone (evaporated), so the dependent variable will be time, in units of seconds or minutes or hours.</span>

Answer: Option (b) is the correct answer.
Explanation:
A spontaneous reaction is defined as the process which tends to occur on its own. It does not require any external factor or force in order to start itself.
For example, when we dissolve KCl in water then potassium chloride being ionic in nature will dissolve on its own. Hence, it will be a spontaneous process.
And, a non-spontaneous reaction is defined as a process for the completion of which we have to provide certain conditions.
Thus, we can conclude that the statement it does not require any external action to begin, is true about a spontaneous process.
