Which of the following sentences has a misplaced modifier?

A misplaced modifier occurs when a descriptive word or phrase is placed too far away from the word it is meant to modify, causing confusion or lack of clarity.

In the chosen option, the phrase "Running late" is intended to describe a person who is late; however, because it is positioned next to "the car," it misleadingly implies that the car is the one that is running late. This creates an awkward and unclear sentence. The intended meaning likely was to indicate that a person was running late due to being stuck in traffic, but as written, it does not convey that meaning clearly.

The other sentences do not have this issue. In those cases, the modifiers clearly describe the subjects without causing confusion. For instance, in the first option, "the cake that was baked by her grandmother" specifies the cake without ambiguity, and in the final two options, the actions are clearly attributed to the correct subjects.
