To determine which pair of symbols represents nuclei with the same number of neutrons, we need to compare the number of neutrons in each symbol.

1. The symbols are 56Co and 58Co. To find the number of neutrons, we subtract the atomic number (protons) from the mass number. In this case, both symbols have the same atomic number (27), but the mass numbers are different. Therefore, they do not represent nuclei with the same number of neutrons.

2. The symbols are 57Mn and 57Fe. Again, we subtract the atomic number from the mass number. In this case, both symbols have the same atomic number (26) and the same mass number (57). Therefore, this pair represents nuclei with the same number of neutrons.

3. The symbols are 57Fe and 58Ni. We subtract the atomic number from the mass number. In this case, the atomic numbers are different (26 and 28), so they do not represent nuclei with the same number of neutrons.

4. The symbols are 57Co and 58Ni. We subtract the atomic number from the mass number. In this case, the atomic numbers are different (27 and 28), so they do not represent nuclei with the same number of neutrons.

Therefore, the pair of symbols that represents nuclei with the same number of neutrons is 57Mn and 57Fe.
