To determine the Regular Price in this scenario, we need to consider both the Subscription Term and the Ranged Discount Schedule applied to the product.

Subscription Term: The Subscription Term provided on the Quote is 12 months, whereas the product's normal Subscription Term is 6 months.
List Price: The List Price of the product is $100 for 6 months.
Discount Schedule: A 25% discount is applied according to the Ranged Discount Schedule for the term of 12 months.
Since the price typically scales with the term, let's first find the total List Price for a 12-month term without any discounts by assuming the base calculation is linear:

Calculate the prorated List Price for 12 months:

Since the List Price of $100 is for 6 months, for 12 months it would be: [ \text{Prorated List Price} = \frac{\text{List Price}}{\text{Initial Term}} \times \text{New Term} = \frac{100}{6} \times 12 = 200 ]
Apply the 25% discount:

With a 25% discount on the $200, the Regular Price (before discount) remains $200 because it's the price calculated before any discounts are applied.
Thus, the correct answer is:

B. Regular Price of $200...
