**Core Concept**
Economic evaluation in healthcare involves comparing the costs and benefits of a program to determine its value and efficiency. This is crucial for resource allocation and decision-making in healthcare policy and management.

**Why the Correct Answer is Right**
The correct answer refers to the process of comparing the costs of a program with its economic benefits. This involves calculating the cost-effectiveness ratio, which is a measure of the cost of a program per unit of benefit gained. In healthcare, this is often expressed as the cost per quality-adjusted life year (QALY) gained. The program with the lowest cost-effectiveness ratio is considered the most cost-effective.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not a recognized term in economic evaluation. It may be a distractor to test the student's knowledge of specific economic evaluation methods.
**Option B:** This option is a type of economic evaluation, but it refers to a specific method rather than the overall process of comparing costs and benefits.
**Option C:** This option is a common economic evaluation technique, but it specifically refers to the process of comparing the costs and benefits of a program over time, rather than the overall comparison of costs and benefits.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that economic evaluation in healthcare involves not only comparing costs and benefits but also considering the opportunity costs of allocating resources to a particular program. Opportunity costs refer to the benefits that could have been gained by allocating resources to an alternative program.

**Correct Answer: B. Benefit-Cost Analysis**
