The method of producing variety of crops by cross breeding the two species of same genus is known as ___________.

Options

A. Inter-varietal hybridization
B. Inter-specific hybridization
C. Inter-generic hybridization
D. Genetic engineering

Explanation

The method of producing a variety of crops by cross-breeding two species of the same genus is known as **inter-specific hybridization**.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a specific term that describes the process of creating new crop varieties through cross-breeding two different species that belong to the same genus.

2. **Identifying the Options**: The options provided include:
- Inter-varietal hybridization
- Inter-specific hybridization
- Inter-generic hybridization
- Genetic engineering

3. **Analyzing Each Option**:
- **Inter-varietal hybridization**: This involves crossing different varieties within the same species, not different species. Therefore, this option is incorrect.
- **Inter-specific hybridization**: This refers to the crossing of different species within the same genus. This is the correct option as it matches the requirement of the question.
- **Inter-generic hybridization**: This involves crossing species from different genera, which does not fit the criteria of the question. Thus, this option is incorrect.
- **Genetic engineering**: This is a broader term that involves manipulating genes but does not specifically refer to the cross-breeding of species. Hence, it is not the correct answer.

4. **Selecting the Correct Answer**: Based on the analysis, the correct term for the method of producing a variety of crops by cross-breeding two species of the same genus is **inter-specific hybridization**.
