The correct answer is:
There must be the same number or fewer prereproductive individuals as there are reproductive individuals
Zero population is the condition where the birth rate and the death rate are equal. The population in this stage is stabilized. To achieve such condition the pre-reproductive individuals count must either equal or less than the reproductive individuals. If the post reproductive members are more than reproductive it is a declining population having death rate higher than birth rate.
If the reproductive members are fewer than pre-reproductive members, the population will not be rising as again death rate is higher than birth rate.
If the reproductive members are fewer than pre-reproductive members, the population will not be rising as again death rate is higher than birth rate.
