The correct answer is: ${ }_1^1 \mathrm{H}=99.985 \% ;{ }_1^2 \mathrm{D}=0.015 \% ;{ }_1^3 \mathrm{~T}=10^{-16} \%$
Isotope of hydrogen is hydrogen -2 (also called) deuterium abbreviated as D.
Which contains one proton and one neutron and has a natural abundance of only $0.015 \%$.
$$
{ }_1^1 \mathrm{H}=99.985 \% ;{ }_1^2 \mathrm{D}=0.015 \% ;{ }_1^3 \mathrm{~T}=10^{-16} \%
