Activities of three radioactive substances A, B and C are represented by the curves A, B and C, in the figure. Then their half-lives $\displaystyle \mathrm{T}_{\frac{1}{2}}(\mathrm{A}): \mathrm{T}_{\frac{1}{2}}(\mathrm{B}): \mathrm{T}_{\frac{1}{2}}(\mathrm{C})$ are in the ratio :
Official answer
(4)
$\displaystyle 2: 1: 3$
