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

Answer

To solve the question, we need to understand the concepts of maximum lifespan and life expectancy.

### Step-by-Step Solution:

1. **Define Maximum Lifespan**:
- Maximum lifespan refers to the longest period that a species can live under ideal conditions. It is a characteristic of the species itself.
- Example: The maximum lifespan of a human is around 120 years.

2. **Define Life Expectancy**:
- Life expectancy, on the other hand, is the average number of years that an individual is expected to live based on statistical averages. This is influenced by various factors such as health, environment, and lifestyle.
- Example: The life expectancy of humans varies by country and can be around 70-80 years.

3. **Identify Characteristics**:
- From the definitions, we can see that maximum lifespan is a characteristic of the **species** because it represents the potential longevity of that species.
- Life expectancy is a characteristic of the **population** because it reflects the average lifespan of individuals within a specific group or population.

4. **Fill in the Blanks**:
- For blank A, we fill in "species".
- For blank B, we fill in "population".

### Final Answer:
- Maximum life span is a characteristic of **species** (A) and life expectancy is characteristic of **population** (B).
