Brown adipose tissue (brown fat) does contain a high concentration of mitochondria, which is correct. However, the brown coloration in brown fat is primarily due to its higher content of iron-containing proteins, particularly cytochromes or referred to as iron-containing cytochrome pigments. These iron-containing proteins in the mitochondria contribute to the brown color and are involved in the process of generating heat. Hence, the correct answer is option 3.
