Nuclear decay occurs spontaneously and is random. Which row gives the correct experimental evidence for these two properties?
- Aspontaneous nature of decay: the decay rate is not affected by pressure; random nature of decay: the decay rate is not affected by temperature
- Bspontaneous nature of decay: the decay rate is not affected by pressure; random nature of decay: the rate at which radiation is received at a counter fluctuates
- Cspontaneous nature of decay: the decay rate is not affected by temperature; random nature of decay: the decay rate is not affected by pressure
- Dspontaneous nature of decay: the rate at which radiation is received at a counter fluctuates; random nature of decay: the decay rate is not affected by pressure
