Answer:
D. While driving without footwear might be dangerous, it is not illegal.
Step-by-step explanation:
The most plausible reason that the police officer did not give Jack a ticket for driving barefooted is that it is not illegal. While it is true that driving without shoes is considered to be dangerous, as it may cause the driver to slip or lose control of the pedals, it is not a violation of the law. The focus of the police officer in this scenario is likely on more serious offenses such as reckless driving, speeding, or impaired driving, rather than on the footwear of the driver. This means that, even though the other driver pointed out that Jack was driving barefooted, the police officer did not issue a ticket as there was no violation of the law in this case.
