B Correct answer
Explanation

When white light passes through a prism, it disperses into a continuous band of seven colors called a spectrum. This happens because different colors (wavelengths) bend at different angles as they enter and exit the prism. The scientific term for this rainbow-like pattern is 'spectrum', not 'color band' or 'color arc'.
