Final answer:
The story of Marie Antoinette's hair turning white is part of historical folklore, though scientifically unlikely due to the nature of hair pigmentation and growth. Option 1.
Step-by-step explanation:
The story of Marie Antoinette's hair turning white overnight is a historical claim suggesting that extreme stress or trauma caused her hair to lose its pigment suddenly before her execution by guillotine.
This phenomenon is known as canities subita. However, scientific understanding indicates that hair whitening in such a short time frame is unlikely, as hair color is determined by melanin, and once hair grows out of the scalp, it does not change color.
Stories like this often become part of historical folklore, reflecting the dramatic events of the time and the emotions surrounding them.
So Option 1.
