(a) all plants
(b) all animals
(c) threatened animals and plants
(d) both (a) and (b)

Options

A. all plants
B. all animals
C. threatened animals and plants
D. both (a) and (b)

Explanation

To solve the question regarding ex situ conservation, we will analyze each option step by step.

### Step 1: Understand Ex Situ Conservation
Ex situ conservation refers to the conservation of species outside their natural habitats. This method is typically used for species that are threatened, endangered, or rare.

### Step 2: Evaluate Each Option
- **Option (a): all plants** - This option suggests that ex situ conservation is used for all plants. However, not all plants require ex situ conservation; it is primarily for threatened or endangered species.

- **Option (b): all animals** - Similar to option (a), this option implies that ex situ conservation is applicable to all animals. Again, this is not accurate as it is mainly focused on threatened or endangered species.

- **Option (c): threatened animals and plants** - This option correctly identifies that ex situ conservation is primarily aimed at conserving threatened or endangered species, whether they are plants or animals.

- **Option (d): both (a) and (b)** - This option suggests that ex situ conservation is used for all plants and all animals, which is not correct as previously explained.

### Step 3: Conclusion
Based on the analysis, the correct answer is **(c) threatened animals and plants**.

### Final Answer
(c) threatened animals and plants
