Answer: Option (d)

Explanation:  

The process of growing plants in culture medium like microorganisms is known as water culture. It is also known as hydroponics. Basically the soil supplies nutrients like nitrogen, water, phosphorus, sulphur, carbon and other essential nutrients.  

This nutrients are all present in the culture medium. Hence even in the absence of the soil, the plants are able to grow in the culture medium. Only the anchorage given by the soil is absent in this case.
