Options

  1. AHalf the time needed for a sample to complete decay.
  2. BHalf the time a sample can be kept before it starts to decay.
  3. CThe time needed for half a sample to decay.
  4. DThe time needed for the rest of a sample to decay one half of it has already decayed.

Correct answer

C. The time needed for half a sample to decay.
