Step-by-step explanation:
The correct statement about service marketing is A. Training current employees better and hiring new ones with more skills can increase service productivity. This is because well-trained and skilled employees are more efficient and can deliver higher-quality services, which can lead to increased customer satisfaction and repeat business. High service productivity can also help a company to differentiate itself in a competitive market.
