Explanation:

To support X - rays as a mutation source, we need to show that X - ray - exposed parents' offspring have more mutations. The other options (no mutations, offspring without mutations, nonlethal mutations) don't support X - rays causing mutations. So the correct choice is offspring with more mutations.

Answer:

offspring with more mutations
