D. A museum has collection of living plants and animals for reference

Answer

To determine which statement among the four provided is correct, we need to analyze each statement regarding taxonomical aids: the key, herbarium, botanical garden, and museum.

### Step-by-Step Solution:

1. **Understanding Taxonomical Aids**:
- Taxonomical aids are tools or resources that help in identifying and classifying organisms. They include keys, herbariums, botanical gardens, and museums.

2. **Analyzing the First Statement (Key)**:
- The first statement claims that a key helps in the identification of any organism "without a character."
- This is incorrect because a key is a set of alternative statements based on specific characteristics of organisms. Therefore, the first statement is false.

3. **Analyzing the Second Statement (Herbarium)**:
- The second statement mentions that a herbarium contains living plant specimens.
- This is incorrect. A herbarium actually contains dried, pressed, and preserved plant specimens, not living ones. Thus, the second statement is false.

4. **Analyzing the Third Statement (Botanical Garden)**:
- The third statement states that a botanical garden has a collection of living plants for reference.
- This statement is correct. Botanical gardens are designed to maintain living plants for educational and research purposes. Therefore, the third statement is true.

5. **Analyzing the Fourth Statement (Museum)**:
- The fourth statement claims that a museum has a collection of living plants and animals for reference.
- This is incorrect because museums typically house preserved specimens (not living) of plants and animals. Hence, the fourth statement is false.

### Conclusion:
After analyzing all four statements, the correct statement is the third one: "A botanical garden has a collection of living plants for reference."
