Preservative treatments increase cedar pole service life from 15 years to more than 30 years.

Explanation:
Interpreting a before/after change in service life means looking for a range that starts with the pre-treatment value and ends with the post-treatment value. If preservative treatments extend cedar pole life from 15 years to more than 30 years, the full span to express that change is from 15 years up to over 30 years. The option that lists exactly that span—15 to more than 30 years—captures both the starting point and the extended endpoint. The other options either start later than 15 or end at a value that does not reflect “more than 30 years,” so they don’t match the described improvement.
