on boiling the egg what structural changes are taking place

On boiling the egg, what structural changes are taking place in the egg white?

A. The colour of the egg changes from colourless to white.

B. $${2^ \circ }$$ and $${3^ \circ }$$ structures are destroyed but $${1^ \circ }$$ structure remains intact.

C. $${1^ \circ },{2^ \circ }$$ and $${3^ \circ }$$ structures of egg are destroyed.

D. A reversible change takes place which can be reversed by decreasing the temperature.

Answer : $${2^ \circ }$$ and $${3^ \circ }$$ structures are destroyed but $${1^ \circ }$$ structure remains intact.

Solution :
During denaturation of proteins, $${2^ \circ }$$ and $${3^ \circ }$$ structures are destroyed but primary structure remains intact.
