Correct answer: Radioactivity

Explanation: ✅ Correct Answer: A) Radioactivity 📚 Explanation: The 'Curie' (Ci) is a traditional unit used to measure the rate of nuclear decay or radioactivity in a sample of material. One curie is defined as exactly $3.7 \times 10^{10}$ disintegrations per second, based on the activity of one gram of radium.
