What about custom fields for dynamic price adjustments

I think in the website, users need to additionally select the warranty status when selecting a product variant. Specific options include:

• Warranty has expired
• Within 1-6 months
• More than 6 months
• inactive

The goal is:

1. Dynamically adjusts product pricing based on the warranty status selected by the customer.
2. Have price changes reflected instantly on product pages.
3. Displays the customer's selected warranty status and adjusted price on the checkout and order confirmation pages.

How can I customize the fields for dynamic price adjustment (any suggestions)? Below is the image:
