Correct option (d) { }_{17}^{35} \mathrm{Cl},{ }_{17}^{37} \mathrm{Cl}

Isotopes are atoms with the same atomic number (Z), but different mass numbers (A). In option d, both ^{35}_{17}\text{Cl}  and ^{37}_{17}\text{Cl} have the same atomic number of 17, but different mass numbers of 35 and 37 respectively, making them isotopes of each other.
