The scientist hypothesizes that prehistoric human ancestors stood upright before they developed sophisticated tools. This is based on the idea that making these tools required the free use of their hands, which standing would have provided.

The scientist assumes that standing up, a sufficient condition for the free use of hands, is also a necessary condition for the free use of hands. In other words, the scientist assumes there is no other way prehistoric human ancestors could have freed their hands without standing. This overlooks alternative explanations, such as sitting, which also allows for hands to be freed.

This does not affect the argument, which is concerned with sophisticated tools, not basic ones.

This weakens the argument. It attacks the assumption that standing up is a necessary condition for the free use of hands, which (B) says is not true. If prehistoric human ancestors made advanced weapons without standing up, they must have freed their hands without standing.

This does not affect the argument, as the scientist does not argue that prehistoric human ancestors stood because they required sophisticated tools.

This does not affect the argument. The scientist argues that prehistoric human ancestors stood before they made tools because they required the free use of their hands, not because standing made their hands more dexterous.

This does not affect the argument. The scientist is concerned with whether the people who made the tools needed to stand, not with whether the people who used the tools needed to stand.
