Solution

The correct option is A denaturation
The destruction of the biological nature and activity of proteins by heat or chemical agent is called denaturation of proteins.

Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds, the primary structure (sequence of amino acids) remains the same after a denaturation process.

It disrupts the normal alpha-helix and beta sheets in a protein and uncoils it into a random shape.

Option B is correct.
