Hint: We know that fertilizers are the chemical substances that are added to the soil to increase fertility of the soil. The increasing fertility of soil results in more crop production. Therefore, fertilizers are necessary in farming.

Complete answer:
There are different types of fertilisers, such as nitrogen fertilisers , phosphorus fertilizers, potassium fertilisers. Some common fertilizers are urea, ammonium sulphate, diammonium phosphate etc. Urea is mostly used nitrogen fertilizer and applied in the field as granules.

Now, come to the question. Here, we have to identify the chemical name of Sindri fertilizer. Sindri fertilizer is the sulphate of ammonia. So, the chemical name is ammonium sulphate ${\left( {{\rm{N}}{{\rm{H}}_{\rm{4}}}} \right)_{\rm{2}}}{\rm{S}}{{\rm{O}}_{\rm{4}}}$.

So, the correct answer is Option B.

Additional Information:
We know that plants also need nutrients for their growth. Three main nutrients of plants are nitrogen, phosphorus and potassium. Fertilizers provide these three nutrients for the growth of plants. Also some other micronutrients such as zinc are also present in some fertilizers that help in growth of plants. We also heard about Rhizobium bacteria that absorbs atmospheric nitrogen and makes the soil fertile. Therefore, Rhizobium bacteria can be called as natural fertilizer.

Note: Remember that there are many disadvantages of fertilizers, such as they cause soil pollution and groundwater pollution. Due to the use of fertilizers, soil will become less fertile overtime. Uses of fertilizers also harm the microorganism present in the soil. Agricultural workers are also badly affected. Sometimes due to raining fertilizers get mixed with water and pollute nearby water bodies to the agricultural fields.
