[A]: Domestication is a type of plant breeding.
[R]: Selection is the basis for the improvement of crops through plant breeding.

Options

A. If both A and R are true and R is the correct explanation of A
B. If both A and R are true but R is not the correct explanation of A
C. If A is true and R is false
D. If both A and R are false

Answer

To analyze the statements provided in the question, we will break down the assertions and reasoning step by step.

### Step 1: Understanding Statement A
**Statement A:** "Domestication is a type of plant breeding."

- **Explanation:** Domestication refers to the process by which humans cultivate and breed plants and animals for specific traits that are beneficial for human use. This process involves selecting plants that exhibit desirable characteristics, such as yield, taste, or resilience, and breeding them to enhance those traits. Therefore, domestication can indeed be classified as a form of plant breeding, as it involves human intervention to improve plant characteristics.

### Step 2: Understanding Statement R
**Statement R:** "Selection is the basis for the improvement of crops through plant breeding."

- **Explanation:** Selection in plant breeding is a crucial process where individuals with desirable traits are chosen for reproduction, while those with less desirable traits are eliminated from the breeding process. This selective breeding leads to the enhancement of specific characteristics in crops, such as increased yield, disease resistance, or improved taste. Thus, selection is foundational to the practice of plant breeding and is essential for the improvement of crops.

### Step 3: Evaluating the Truth of Both Statements
- **Truth of Statement A:** True. Domestication is indeed a type of plant breeding.
- **Truth of Statement R:** True. Selection is a fundamental method used to improve crops through plant breeding.

### Step 4: Determining the Relationship Between A and R
- Since both statements are true, we need to assess if Statement R correctly explains Statement A. The explanation provided indicates that domestication involves selection as a method to improve plants, thereby making R a valid explanation for A.

### Conclusion
Both statements A and R are true, and R is the correct explanation of A. Therefore, the final answer is: **Both A and R are true, and R is the correct explanation of A.**
