A radioactive substance (parent) decays ...

A radioactive substance (parent) decays to its daughter element . The age of radioactive substance (t) is related to the daughter (d)/parent (p) ratio by the equation :
a) `t=(1)/(lambda) "In" (1+(p)/(d))`
b) `t=(1)/(lambda) "In" (1+(d)/(p))`
c) `t=(1)/(lambda) "In" ((d)/(p))`
d) `t=(1)/(lambda) "In" ((p)/(d))`

A

`t=(1)/(lambda) "In" (1+(p)/(d))`

B

`t=(1)/(lambda) "In" (1+(d)/(p))`

C

`t=(1)/(lambda) "In" ((d)/(p))`

D

`t=(1)/(lambda) "In" ((p)/(d))`
