A:  For the ant to be 100 times as big as it used to be, it would logically be 100 times as long.  That means its length would be found `2cmxx100=200cm=2m`

B:  For the ant to be 100 times as big, it would logically have 100 times as much mass so `.0003kgxx100=.03kg`

C:  Since ants can lift 10 times their own mass plus their own body mass, `.03kgxx10+.03kg=.33kg` and if you're interested `.0033kgxx100=.33kg`

D:  I believe that a 2 meter ant could be quite dangerous.  Although it couldn't lift much, compared to a similar size "Bobcat" machine, Ants pose other dangers.  Ants are colony insects so the ant would seek to get back to its original colony.  Killing it would be the only way to stop it.  In addition, some species of ants have stinging hairs that would be harmful to anyone who happened to get too close.  That's why Brazilian Fire Ants are dangerous, even without being 2 meters long.  As for being able to lift its own mass, as calculations in B and C prove, that's a trick question.
