Answer:
D: Increasing the amount of water.
Explanation:
Choice A: increasing the pressure can force the liquid to stay a liquid and affect the boiling point (decrease it).
Choice B and C: both involve colligative properties, adding a solute to water will increase the boiling point of water.
Choice D: just having more water does not change the boiling point of the water as this minimize the effect of any external factor.
<em>So, the right choice is: D: Increasing the amount of water.</em>
