The use of machinery in agriculture helps to
(i) increase the quantity of crop yield (ii) get the job done faster (iii) reduce the dependency on human and animal labour

Options

A. (i) and (ii)
B. (i) and (iii)
C. (ii) and (iii)
D. (i), (ii) and (iii).

Explanation

**Step-by-Step Solution:**

1. **Understanding the Role of Machinery in Agriculture:**
- Machinery plays a crucial role in modern agriculture. It enhances the efficiency and effectiveness of farming practices.

2. **Increasing Crop Yield:**
- The use of machinery can lead to an increase in the quantity of crop yield. This is because machines can perform tasks such as planting, watering, and harvesting more efficiently than manual labor, allowing for better management of crops and ultimately leading to higher production.

3. **Speeding Up Agricultural Processes:**
- Machinery helps in getting agricultural jobs done faster. For example, tractors can plow fields much quicker than traditional methods, and harvesters can collect crops in a fraction of the time it would take to do so by hand.

4. **Reducing Dependency on Labor:**
- The use of machinery reduces the dependency on human and animal labor. With machines taking over many of the labor-intensive tasks, farmers can rely less on manual labor, which can be particularly beneficial in areas where labor is scarce or expensive.

5. **Conclusion:**
- Therefore, the use of machinery in agriculture helps to (i) increase the quantity of crop yield, (ii) get the job done faster, and (iii) reduce the dependency on human and animal labor. All three statements are correct.

**Final Answer:**
All three statements (i), (ii), and (iii) are correct.
