Answer:
c. 2
Explanation:
Given that
Parent to daughter ratio = 1:3
Based on the above information, after considering the 1 half-life of radioactive isotope there is one-half of the real radioactive atoms of the parent left also the equivalent number of daughter atoms produced
Therefore after one half, the ratio between parent and daughter atom is 1:1
Now after the second half, half of the left parent atom would be transformed into the daughter cells
This remains a quarter of parent atom and 3 quarter of daughter atoms
So, the ratio of 1:3 would be shown after 2 half-lives
