From the given data and options, the most reasonable conclusion that can be drawn is:
As the amount of ice added increases, the change in temperature increases.
This conclusion is supported by the data in the table, where higher amounts of ice seem to produce a larger decrease in temperature. For example, in sample 4, the highest amount of ice (122.6 grams) results in a significant drop in temperature from 14.6°C to 3.3°C, compared to the other samples with less ice.
The other options provided do not correctly reflect the relationships observed in the table.
