Final answer:
The minimum parking distance from a train track in a restricted area depends on local laws, with an educated guess being 5 meters; however, the exact distance should be verified with local traffic regulations.
Step-by-step explanation:
The minimum parking distance between you and a train track in a restricted area can vary depending on the local laws and regulations. However, for safety reasons, it is commonly suggested to keep a substantial distance to ensure that in case a train passes by, it does not pose a danger to you or your vehicle. While this question may be part of a broader set of driving test questions that also involve Mathematics, such as calculating stopping distances and judging safe crossing times, the specific regulation pertaining to the parking distance from train tracks is a matter of law and may differ from place to place. Therefore, it's essential to consult your local traffic laws for the accurate answer. In the case of the provided options and without specifying a particular jurisdiction, an educated guess would be (b) 5 meters, but this is only an assumption and should be verified against actual regulations.
