C. A.Species B.Population
D. A.Species B.Individual

Answer

To solve the question, we need to identify the correct terms that correspond to the definitions provided for maximum lifespan and life expectancy.

### Step-by-Step Solution:

1. **Understanding Maximum Lifespan**:
- Maximum lifespan refers to the longest period that a member of a species can live under ideal conditions. It is a characteristic of a specific species. For example, the maximum lifespan of a crow is typically between 10 to 15 years.
- Thus, we can conclude that maximum lifespan is a characteristic of a **species**.

2. **Understanding Life Expectancy**:
- Life expectancy, on the other hand, is the average period that a member of a population is expected to live based on statistical averages. It takes into account various factors such as health, environment, and lifestyle.
- Life expectancy is typically discussed in terms of a **population**. For example, if we consider a population in a specific region, we can calculate the average lifespan of individuals within that population.

3. **Filling in the Blanks**:
- Based on the above understanding, we can fill in the blanks:
- A: **Species**
- B: **Population**

4. **Final Answer**:
- Therefore, the complete statement is: "Maximum life span is a characteristic of **species** and life expectancy is characteristic of **population**."
