The correct option is the funnel because it provides a controlled and precise way to pour liquids into the air meter without splashing or overfilling. Using a funnel helps to ensure that the initial quantities of water and alcohol are measured accurately, which is crucial for obtaining reliable results in air content tests. It minimizes the risk of spills and allows for a clearer view of the liquid levels entering the meter, ensuring that the process adheres to proper testing protocols.

Options such as a measuring cup might not provide the same level of precision when pouring, especially if the goal is to avoid any mess or loss of material. Pouring directly from the bottle can lead to inaccuracies and potential spillage, compromising the integrity of the test. A spatula is not suitable for liquid measurement as it is designed for solid materials, thus being ineffective for this particular task.
