Environmental barriers impede entrepreneurial activities. These external factors, such as the lack of raw materials, insufficient machinery, or delayed financial resources, complicate the establishment and efficient operation of ventures. Conversely, the availability of skilled labour is not a hindrance but a facilitator. Ample skilled labour empowers entrepreneurs to implement their strategies effectively. Consequently, only the availability of skilled labour signifies a beneficial condition, not an impediment. Therefore, the correct response is Availability of skilled labour.
