The half life of a radioactive substance is `T_(0)`. At `t=0`,the number of active nuclei are `N_(0)`. Select the correct alternative.

A

The number of nuclei decayed in time internal `0-t` is `N_(0)e^(-lambda t)`

B

The number of nuclei decays in time interval `0-t` is `N_(0) (1-e^(-lambda t))`

C

The probability that a radioactive nuclei does not decay in interval `0-t` is `e^(-lambdat)`
