• D. Bipedal gait and binocular vision

Answer 1

The correct option is C Increases in carnival capacity

• The devel­op­ment of the brain enabled hominids to make and use tools and fire, com­mu­ni­cate using lan­guage, devel­op cul­ture and soci­ety, adapt to new envi­ron­ments and, final­ly, to become self-aware and creative.
  

So, the correct option is 'Increases in carnival capacity'.
