Which one of the following best describes the overall shape of the binding-energy-per-nucleon curve from hydrogen (A=1) to uranium (A≈238)?
a) It remains almost constant for all mass numbers.
b) It shows several small peaks at magic numbers, giving an oscillatory pattern with mass number.
c) It rises rapidly to a broad maximum around A≈56 and then falls slowly for heavier nuclei.
d) It falls steadily as mass number increases.
