Options

  1. AD
  2. BC
  3. CA
  4. DB

Correct answer

C. A

Step-by-step solution

By law of radioactive decay -dNdt∝λNN\frac{\mathrm{dN}}{\mathrm{dt}} \propto \lambda \mathrm{N} \mathrm{N} is the number of radioactive nuclei in the sample So, dNdt\frac{\mathrm{dN}}{\mathrm{dt}} can be negative The variation of decay rate with number of active nuclei is shown by the graph
