C. `(""_(2)He^(3), ""_(1)H^(3)), (""_(1)H^(2), ""_(1)H^(3)) and (""_(79)Au^(197), ""_(80)Hg^(198))`
D. `(""_(1)H^(2), ""_(1)H^(3)), (""_(2)He^(3), ""_(1)H^(3)) and (""_(79)Au^(197), ""_(80)Hg^(198))`

Answer

D

Explanation

Isotope `rarr` same atomic number, but different mass number i.e., `(""(1)H^(1), ""_(1)H^(3))`
Isobar `rarr` same mass number, but different atomic number i.e., `(""_(2)He^(3), ""_(1)H^(3))`
Isotone `rarr` same neutron number but different atomic number. i.e `(""_(79)Au^(197), ""_(80)Hg^(198))`
