Clear B man.good question this.

B and C are the main contenders

B - Says why D.g population is less

C - Restates what is already given in the passage(D.g reproduces faster).Hence incorrect.

IMO the answer is B. Because only B gives a reason to why the population of D.G would decrease and D.H would remain unaffected.

Even though D. galeata grows and reproduces much faster, its population is often outnumbered by D. hyaline.

Option B says Predators of Zooplankton D. zylen live and feed near surface during the day. Predators are feeding on D.Z. not on D.G.
Then how would population of D.G. reduce?

Please clear my confusion.

The predators are of zooplankton and not of any specific kind. During day G is near the surface so predators eat more G.

Two possible explanations:

1. No. of eggs laid / offsprings produced by DH >DG:
Ans choice E is opposite to this info.

2. Life-span of DH >DG: Ans choice B.

Hence, IMO, Ans is choice B
