Since the human eye can see only the visible spectrum of light which is perceived in the form of luminous flux and thus lumen.
Thus, the lumen is the correct answer.

Massive elephants and rhinos, sabre-tooth cats and lions, horses and deers quickly got populated in Earth's plains and forests.
a frameshift mutation would likely have a larger effect because it changes many codons.
(*a point mutation might also have a large effect, for example, if it changes a codon for an amino acid into a stop codon)
