Parasitic wasps lay their eggs directly into the eggs of various host insects in exactly the right numbers for any suitable size of host egg. If they laid too many eggs in a host egg, the developing wasp larvae would compete with each other to the death for nutrients and space. If too few eggs were laid, portions of the host egg would decay, killing the wasp larvae.
Which of the following conclusions can properly be drawn from the information above?
The size of the smallest host egg that a wasp could theoretically parasitize can be determined from the wasp's egg-laying behavior.
Host insects lack any effective defenses against the form of predation practiced by parasitic wasps.
Parasitic wasps learn from experience how many eggs to lay into the eggs of different host species.
Failure to lay enough eggs would lead to the death of the developing wasp larvae more quickly than would laying too many eggs.
Parasitic wasps use visual clues to calculate the size of a host egg.
只有我觉得D对么……少产卵的话，寄主的蛋会腐烂，wasp在幼虫larvae时期就死了，产的卵多的话，developing wasp larvae，就是长大了的wasp幼虫才会互相竞争，是larvae 阶段之后了，所以少产卵幼虫死得比多产卵幼虫快啊……为什么我觉得很合理
