Manganese dioxide (MnO₂) is black in color.
Explanation:
Manganese dioxide is a dark, black crystalline compound that occurs naturally as the mineral pyrolusite. It is commonly used as a depolarizer in dry cell batteries, a pigment in ceramics and glass, and an oxidizing agent in various chemical reactions.
Option A (Black): Correct, as MnO₂ is black in color.
Option B (Blue): Incorrect, as this color is not characteristic of manganese dioxide.
Option C (Brown): Incorrect, though some manganese compounds can be brown, MnO₂ specifically is black.
Option D (Green): Incorrect, as manganese dioxide is not green in color.
Therefore, the correct answer is: A) Black.
