The correct answer is option'e':All of the options are correct

Explanation:

A buffer solution is a solution that resists a change in it's pH and is formed by mixing a weak acid and it's conjugate base or by mixing a weak base and it's conjugate acid.

In blood stream a buffer of carbonic acid and bicarbonate anion this maintaining pH in the blood stream.

Buffers are present in many biological systems such as blood, phosphate buffer, hemoglobin buffer, e. t. c.

Thus a buffer is essential in water bodies such as lakes resisting a change in pH and the buffer is formed by dissolved carbon dioxide.
