The correct option is 1, 3 and 4 only, as these applications of Artificial Intelligence (AI) are well-established and actively utilized in various sectors. AI can optimize energy consumption in industrial units by analyzing usage patterns and suggesting efficiencies (1). It is also capable of assisting in disease diagnosis by analyzing medical data and recognizing patterns indicative of specific conditions (3). Furthermore, AI-driven algorithms are effectively employed in text-to-speech conversion, enhancing accessibility and communication (4). In contrast, creating meaningful short stories and songs involves complex human emotions and nuances that current AI technologies struggle to replicate authentically, while the wireless transmission of electrical energy is a different area of technology not primarily reliant on AI.
