What is characteristic of the euphotic zone?
A) low levels of phosphate and nitrates
B) high levels of dissolved oxygen (O₂)
C) high levels of carbon dioxide (CO₂)
D) a low amount of sunlight
Euphotic Zone
The upper layer of a body of water that receives sufficient sunlight for photosynthesis, where most aquatic life is concentrated due to the availability of light.
Phosphate
A chemical compound that is vital for plant growth and is used extensively in fertilizers.
Nitrates
Inorganic compounds made of nitrogen and oxygen, NO3−, that are often used as fertilizers but can contribute to water pollution if overused.

Final Answer :
B
Explanation :
The euphotic zone is the upper layer of the ocean where there is enough sunlight for photosynthesis to occur. Therefore, it is characterized by high levels of dissolved oxygen (O₂) due to the photosynthetic activity of phytoplankton.
