Explanation:

A physical change is one that alters the form or appearance of a substance without changing its chemical composition. Boiling, frying, and scrambling eggs involve chemical reactions that change the chemical structure of the egg - proteins denature. Cracking an egg only changes its physical form by breaking the shell, without altering the chemical nature of the egg's contents.

B. Cracked
