Question

Neeraja decided to sow four plants marked A, B, C and D. She used wastewater from different sources given in the table below to water these plants. Among these, which plant will grow well?
$$\begin{array}{cc}\text{Plant}& \text{Water source}\\ \text{A}& \text{Wastewater from kitchen}\\ \text{B}& \text{Wastewater containing mild detergents}\\ \text{C}& \text{Wastewater containing strong detergents}\\ \text{D}& \text{Wastewater from car washing facility}\end{array}$$

• A. Plant A
• B. Plant B
• C. Plant C
• D. Plant D

Answer 1

The correct option is A Plant A

Plants need water and nutrients to grow. Plant B and plant C is supplied with water which contains heavy soaps and detergent which are harmful to plants. Water from car washing facilities contain oil and grease which comes out while washing cars. Oil and grease hinder the proper growth of plant D because they pollute the water.
However, water from the kitchen contains organic nutrients required for the growth of a plant. Hence, plant A grows well compared to others.
