If birth rate increases in a population then size of population will also increase. Thus, the population will have high growth rate. If the death rate in the population falls, there is no fall in the birth rate, then there will be high growth rate in the population size.
In addition, if the birth rate falls to equal the death rate in a population, then the population growth stops. A phase where birth rate equals the death rate is called demographic transition.
Hence the correct answer is option (d) 11 and 111 only.
