Which zone is the dimly lit (twilight) zone of the sea?
A) the bathyal zone
B) the coastal zone
C) the abyssal zone
D) the euphotic zone
Twilight Zone
The twilight zone refers to the deep region of the ocean lying below the sunlit surface waters but above the dark abyss, characterized by minimal light penetration.
Bathyal Zone
relates to the part of the ocean's pelagic and benthic zones that extends from the edge of the continental shelf to the abyssal zone, characterized by minimal light penetration and a diversity of specialized organisms.
Coastal Zone
The interface where the land meets the ocean, encompassing shoreline environments as well as adjacent coastal waters, characterized by its unique biological and physical attributes.

Final Answer :
A
Explanation :
The bathyal zone is the dimly lit (twilight) zone of the sea, located between the euphotic zone and the abyssal zone. It receives very little sunlight and has reduced levels of oxygen compared to the euphotic zone above, making it a challenging environment for marine life to survive. The coastal zone, on the other hand, refers to the shallow water that extends from the shore to the continental shelf, while the abyssal zone is the deep, dark region beyond the continental shelf. The euphotic zone, sometimes called the sunlit zone, is the upper layer of the ocean where photosynthesis can occur and receives abundant sunlight.
