B It requires two different dyes
C It produces color contrast and imparts the same color to all bacteria in the smear

Option C is the correct answer.

Detailed Explanation

Simple staining uses a single dye to stain all cells in a smear, producing color contrast to make the cells visible under a microscope.

Hint

Consider the primary purpose and method of simple staining, which involves using a single basic dye.
