# Which of the following is used as Bioremedies

$\begin{array}{1 1}(a)\;Nitrates\;and\;phosphates\\(b)\;Enzymes\;and\;microorganisms\\(c)\;Sediments\;and\;oils\\(d)\;Oxides\;of\;nitrogen\end{array}$

Enzymes are biological catalysts that facilitate the conversion of substrates into products by providing favorable conditions that lower the activation energy of the reaction
The process of bioremediation mainly depends on microorganisms which enzymatically attack the pollutants and convert them to innocuous products.
Hence B is the correct answer.
