different isotopes of an element have different numbers of
protons
hadrons
photons.
neutrons

Explanation:

Isotopes of an element have the same number of protons (defining the element) but differ in neutron count. Protons determine the element, hadrons are subatomic particle types (not specific to isotope difference), and photons are light particles. So isotopes differ in neutrons.

Answer:

D. neutrons (assuming the last option is D; if options are labeled as per the order: the option "neutrons" is the correct one, so if the options are A. protons, B. hadrons, C. photons, D. neutrons, then Answer: D. neutrons)
