Final answer:
The weak and strong nuclear forces are not experienced directly because they have a short range and primarily occur inside atomic nuclei.
Step-by-step explanation:
The weak and strong nuclear forces are not experienced directly because they only act over very small distances, comparable to the size of an atomic nucleus or less. These forces have a short range and primarily occur inside atomic nuclei. Therefore, option c) The forces are short-ranged and act inside atomic nuclei, is the correct answer.
