Answer

To determine which of the following is an introduced variety of crop, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Introduced Variety"**:
- An introduced variety of crop refers to a type of crop that has been brought into a region from another area, often for agricultural purposes. These varieties are typically bred or selected for specific traits such as yield, disease resistance, or adaptability to local conditions.

2. **Identify the Options**:
- We need to look at the options provided in the question (though not listed here) to identify which crops are considered introduced varieties.

3. **Research the Varieties**:
- Investigate the varieties mentioned in the options. For example:
- **ICAR**: Refers to the Indian Council of Agricultural Research, which is involved in developing new varieties but is not a crop itself.
- **Soya**: Commonly known as soybean, it is indeed an introduced variety in many regions, including India.
- **Sonora 64**: This is a wheat variety that has been introduced and is known for its high yield potential.

4. **Evaluate the Options**:
- Compare the identified varieties against the definitions and characteristics of introduced varieties.
- Confirm that both Soya and Sonora 64 are recognized as introduced varieties.

5. **Select the Correct Answer**:
- Based on the evaluation, if the options include Soya and Sonora 64, either or both can be considered correct. However, if the question asks for a single introduced variety, then Sonora 64 is often highlighted as a significant introduced variety.

### Final Answer:
- The correct answer is **Sonora 64**, as it is an introduced variety of crop.
