Answer
The correct answer is C. They contribute positively to growth.
Explanation
The question focuses on the concept of injector factors in an economic system, which are elements that contribute positively to economic growth and development. These factors typically include investments, government spending, and exports, which stimulate demand and enhance economic activity.
Here are further explanations.
- Option A: They reduce economic activity. This is incorrect because injector factors are meant to increase economic activity, not reduce it.
- Option B: They create a balanced economy. While injector factors can contribute to a balanced economy, this option is too vague and does not specifically address the direct impact of injectors on economic growth.
- Option C: They contribute positively to growth. This option accurately describes the role of injector factors, as they are essential for stimulating economic growth and increasing overall demand.
- Option D: They lead to inflation. Although excessive injectors can lead to inflation, this is not their primary role. The main purpose of injectors is to foster growth rather than cause inflation.
