Final Answer :
B
Explanation :
The number of neutrons in an isotope is calculated by subtracting the atomic number (number of protons) from the mass number. For 2759Co{ }_{27}^{59} \mathrm{Co}2759Co , the atomic number is 27 and the mass number is 59. Therefore, the number of neutrons is 59 - 27 = 32.
