Explanation

According to the Official UPSC Answer Key (Series A), the correct answer is Option B (1, 3 and 4 only).

– 1. Bring down electricity consumption in industrial units (Correct): AI-powered dynamic building management systems, predictive load forecasting, and automated process optimization actively reduce HVAC and heavy machinery power consumption.
– 3. Disease diagnosis (Correct): Machine learning models and computer vision systems effectively assist clinicians by analyzing medical imaging (such as X-rays, MRI scans, and retinal images) to detect pathologies and tumors.
– 4. Text-to-Speech Conversion (Correct): Natural language processing and deep learning acoustic models reliably transform written text into natural human speech across multiple digital platforms.
– 2. Create meaningful short stories and songs (Incorrect as per UPSC): UPSC did not accept creative artistic generation of meaningful narrative stories and musical compositions as an established, effective capability in the current state of technology at the time.
– 5. Wireless transmission of electrical energy (Incorrect as per UPSC): Wireless power transmission relies primarily on electromagnetic inductive and resonant coupling technologies (physics/hardware), rather than being an intrinsic functional capability of Artificial Intelligence software.

Therefore, statements 1, 3, and 4 are correct — Option B.
