Answer:
We can immediately cross-out C
We can also cross-out A.
Now we have B and D. Commensalism and Mutualism. Now, commensalism is an association between two organisms in which one benefits and the other derives neither benefit nor harm.
Mutualism is the doctrine that mutual dependence is necessary to social well-being.
I would say D: Commensalism. Both fish can survive without each other.
Spectral analysis proposes that there is no hydrogen fusion roughly
speaking. They are hot since they are very thick. So if you are a convinced
high density and temperature and still not doing synthesis, you must be small.
Also, stellar evolution models are founded on the observation of planetary
nebulae, where stars have shed most of their mass after being red giants. The
physics designates a small, hot, central remainder.

Explanation:
Average weight before selection =2.5 kg
Average weight after selection = 5.5 kg
Average weight in the next generation =3.5kg
= 
R= Mean weight in the next generation - mean weight before selection
= 3.5-2.5 = 1.0
S= Mean weight after selection -mean weight before selection
= 5.5 - 2.5 = 3.0
= = 
= 0.33
