This checks a science current affairs fact about a human ancestor species discovery announced around 2015.
Homo Naledi: correct. Scientists in South Africa announced the discovery of Homo naledi, a small bodied hominin species with a small brain, found in the Rising Star cave system.
Dwarf Sapein: wrong, this is not a real scientific name, just a made up sounding term to confuse you.
Dwarf Homo Sapein: wrong, this again is not a genuine species name, and it wrongly implies the new find is a variant of modern humans (Homo sapiens), which it is not.
None of the above: wrong, since the correct name is listed among the options.
