The dependent variable in this statement is distance a softball is thrown.

Here's why:

The dependent variable is the one that you measure or observe in response to changes in the independent variable. In this case, you're comparing how far the softball is thrown by different groups (girls and boys). The distance the softball travels is what you're measuring, and it "depends" on the group (gender) being studied.

The other options are:

A.Weight of softball: This would likely be a controlled or fixed variable if you are testing how gender influences distance, as the weight of the ball would typically remain constant for both groups.
