Final answer:
The use of studded tires is governed by regional laws and the period during which they are illegal varies. A typical restriction period is from October 1 to April 30, though it's important to check local regulations.
Step-by-step explanation:
The legality of studded tires depends on the state or region's specific laws regarding their usage. Generally, studded tires are permitted during the months where icy and snowy road conditions prevail to provide additional traction. Without specific regional information, it's not possible to state definitively which option (A, B, or C) is correct as the period during which studded tires are illegal varies by location. However, option B (October 1 and April 30) is a common timeframe in many areas where studded tires are allowed during the winter months and prohibited during the warmer months to protect road surfaces from damage.
