The correct answer to the question is:
Multiyear level term.
Explanation:
1. A straight term policy is also known as a multiyear level term policy.
2. This type of policy provides coverage for a specific term length (e.g., 10 years, 20 years) with a level premium that remains the same throughout the term.
3. The coverage amount and premium do not change during the term of the policy, hence the term "level."
4. This policy is different from renewable term, limited payment, decreasing term, or conversion term policies due to its specific characteristics of a fixed term length and premium amount.
