भारताने आजपर्यंत किती आण्विक चाचण्या केल्या ?

The correct answer is Option A (Two).

Key Points:
• India is a declared nuclear-armed state. The history of India's nuclear weapons program centers around major test operations at the Pokhran test range in Rajasthan.
• The question refers to the distinct *series/operations* of nuclear tests rather than the individual explosive devices detonated.
• History of Indian Nuclear Tests:
• 1. First Test Operation (1974): Codenamed Smiling Buddha (Pokhran-I). Conducted on May 18, 1974, under PM Indira Gandhi. It was a single peaceful nuclear explosion.
• 2. Second Test Operation (1998): Codenamed Operation Shakti (Pokhran-II). Conducted on May 11 and 13, 1998, under PM Atal Bihari Vajpayee. Although this operation consisted of 5 distinct bomb detonations, it is collectively counted as India's second nuclear test event.
• Historically and officially, India has conducted TWO major nuclear testing operations. Therefore, Option 1 is correct.
• Key Takeaway: India has conducted two major nuclear test operations: Pokhran-I (Smiling Buddha) in 1974 and Pokhran-II (Operation Shakti) in 1998.
