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:

The correct answer is 1, 3 and 4 only.

Let us analyze the capabilities of Artificial Intelligence (AI) with respect to the given statements based on the current state of technology development:

Statement 1: Bring down electricity consumption in industrial units (Correct)
AI is widely used to optimize energy consumption. By using machine learning algorithms, smart grids, and predictive maintenance, AI can analyze real-time data from sensors in industrial machinery and HVAC systems to adjust operations, minimize waste, and significantly lower energy use.

Statement 2: Create meaningful short stories and songs (Incorrect for this specific key)
While modern generative AI models (like Large Language Models) can generate creative-looking text, short stories, and music lyrics, standard UPSC/exam answer keys (from the time this question was originally set, typically CSE 2020) consider the creation of truly "meaningful" original creative work to be outside the definitive capability of standard AI systems, or they categorize it as imitation rather than genuine comprehension and creation. Following the provided correct option, this statement is excluded.

Statement 3: Disease diagnosis (Correct)
AI has achieved high accuracy in medical diagnostics. Machine learning models, particularly computer vision algorithms trained on medical imaging (such as X-rays, MRIs, and CT scans), are highly effective at identifying conditions like cancer, diabetic retinopathy, and cardiovascular anomalies.

Statement 4: Text-to-Speech Conversion (Correct)
Text-to-Speech (TTS) conversion is a mature and standard application of AI. Deep learning models process written text and synthesize natural-sounding human speech, which is commonly used in virtual assistants, navigation systems, and accessibility tools.

Statement 5: Wireless transmission of electrical energy (Incorrect)
Wireless power transmission is a physical and electrical engineering technology (relying on electromagnetic induction, resonance, or microwaves) rather than a software-driven artificial intelligence application. AI cannot perform wireless energy transmission.

Thus, statements 1, 3, and 4 are correct applications of AI under the specified constraints, making 1, 3 and 4 only the correct choice.
