D) 2655Fe{ }_{26}^{55} \mathrm{Fe}2655Fe
Isotope
Variants of a particular chemical element which differ in neutron number, and consequently in nucleon number, but have the same number of protons.
- Become familiar with the atomic framework, specifically the inclusion of protons, neutrons, and electrons.
- Understand the symbols and atomic numbers of frequently encountered elements.
- Gain insight into the correlation between atomic number (Z), mass number, and isotopic diversity.

Final Answer :
D
Explanation :
The element with atomic number (Z) 26 is iron (Fe), and with 29 neutrons, its mass number (A) is Z + neutrons = 26 + 29 = 55, making it 2655Fe{ }_{26}^{55} \mathrm{Fe}2655Fe .
