A being towed
B aground
C at anchor
D drilling
AI Explanation

The correct answer is A) being towed. The day-shape shown in illustration D010RR indicates that the mobile offshore drilling unit is being towed. This is in accordance with the International Regulations for Preventing Collisions at Sea (COLREGS), which require vessels being towed to display a black ball shape where it can best be seen. The other answer choices are incorrect because the day-shape does not indicate the unit is aground (B), at anchor (C), or actively drilling (D). The specific day-shape is used to communicate the unit's status of being under tow to other vessels in the area.
