c. Birth rates are high      
Explanation:

From the graph, it can also be concluded that narrow tip at the top shows that lesser older people are in the population.
This pyramid shown in the diagram is a triangular age pyramid. In this type of pyramid the pre-reproductive individuals are high   reproductive individual are moderate and non-reproducing individual is less. In such pyramid we find population grows.
Suppose in a family of ten 6 are pre-reproductive, 2 moderate reproductive and 2 post-reproductive. We will see the in the course of moderate and post-reproductive will die and those six of pre-reproducing age will increase the population.
