With the present state of development, Artificial Intelligence can effectively do which of the following ? 1. Bring down electricity consumption in industrial units 2. Create meaningful short stories and songs 3. Disease diagnosis 4. Text-to-Speech Conversion 5. Wireless transmission of electrical energy Select the correct answer using the code given below :

Option (b) is correct because AI is effectively used for optimizing energy grids to reduce consumption (1), identifying patterns for medical diagnosis (3), and natural language processing for text-to-speech conversion (4). Option (d) is the most tempting wrong choice, but it is incorrect because wireless power transmission (5) is a physical engineering technology based on electromagnetism rather than AI, and at the time of the exam, AI's ability to create truly "meaningful" creative content (2) was considered limited. The core concept being tested is the practical application of data-driven algorithms versus physical hardware technologies and high-level human creativity.
