Solution
The correct options are
C Hydroponics
D Aeroponics
Plants can be grown without soil using hydroponics or aeroponics. These methods are particularly useful in places where space is a constraint and it is difficult to get good soil for growing plants. In hydroponics plants are grown in a nutrient solution. In aeroponics, plants are grown in such a way that their roots grow into the air and nutrients are directly sprayed on the roots.
