#=C=4km##/h#

Explanation:

The gazelle is travelling at #2km##/0.5hours#. One half hour is equal to #0.5# hours. Speed is measured as #km##/h#. To go from 0.5 hours to 1 hour you need to multiply it by 2, #0.5*2=1#. Because you multiply the time by two, you need to multiply the distance by 2. #2*2=4#.

Therefore the speed of the gazelle is 4km/h, and the correct answer is C.
