Choose the wrong pair

Options

A. Salvadora – Desert
B. Cenchrus – Savanna
C. Abies – Coniferous forest
D. Tectona – Temperate forest

Explanation

To solve the question "Choose the wrong pair" regarding which plants are commonly found in temperate coniferous forests, we will analyze each option provided:

1. **Quercus (Oak)**:
- Quercus is commonly known as oak. It is primarily found in temperate deciduous forests and evergreen tropical forests. Since temperate coniferous forests are characterized by evergreen conifers with needle-like leaves, Quercus does not belong here. Therefore, this is a wrong pair.

2. **Dipterocarpus**:
- Dipterocarpus is a genus of trees that are typically found in tropical rainforests, particularly in Southeast Asia. Similar to Quercus, it does not belong in temperate coniferous forests. Thus, this is also a wrong pair.

3. **Shorea robusta**:
- Shorea robusta, commonly known as Sal, is primarily found in tropical deciduous forests. As deciduous forests shed their leaves, this tree type does not fit into the category of temperate coniferous forests. Hence, this is another wrong pair.

4. **Pinus walshiana**:
- Pinus walshiana is a coniferous tree that is indeed found in temperate coniferous forests. It has needle-like leaves and cones, making it well-adapted to the environment of temperate coniferous forests. Therefore, this is the correct pair.

### Conclusion:
The wrong pairs among the options provided are:
- Quercus (Oak)
- Dipterocarpus
- Shorea robusta

The correct answer is **Pinus walshiana**, which is the only plant that is commonly found in temperate coniferous forests.
