Vapor is your answer my friend
I hope this helps
I have read the question several times and I believe "A.The kelp draws nutrients from the water rather than the soil, which it does not have available." would be your answer.
Although it is true that kelp is temperature sensitive, the question states that "They use a temperature regulation system to keep the water temperature at about 12°C." So even with the added addition of sunlight, I think the temperature still stays generally the same. And as long as the temperature is between 5-20 C degrees, the kelp should be okay.
However, kelp does not work the same as most land plants, kelp does not have a root system. It instead has a "holdfast" anchoring system that does not transport nutrients. So how does kelp get nutrients? From the water directly. Since the question says nothing about nutrients in the water, and directly talks about nutrients in the soil, we can assume that their is no nutrients in the water (only in the soil). Making A our answer.
This is a copy/pasted answer from a question I also answered.

Answer:
b. region of DNA consisting of the promoter, the operator, and coding sequences for structural proteins.
Explanation:
Operon is a segment of DNA that carry groups of genes coding for related proteins. An operon consists of an promoter, operator and coding sequences for structural proteins (regulatory and structural genes).
The promoter is the region in operon where RNA polymerase binds and initiates the process of transcription.
Regulatory DNA sequences are binding sites for regulatory proteins that control the expression of the operon "up" or "down." and structural genes code for proteins needed for cell function such as lactose metabolism.
Regulatory proteins acts as a repressor and when bind to operator, blocks the forward movement of RNA polymerase on the DNA.
Hence, the correct option is b.
