Which of the following statements best explains the changes in the size and composition of the population of finches after the drought?

Incomplete question. The full question reads;

The graphs above show the population size and distribution of beak sizes in a finch population on the island of Daphne Major in the Galapagos in 1976 and 1978. Smaller-beaked finches are better suited for eating grasses and small seeds. Larger-beaked finches are better suited for cracking larger seeds and nuts. In 1977 a drought took place and the vegetation of the island was affected by the lack of rain.

Which of the following statements best explains the changes in the size and composition of the population of finches after the drought?

a. The total number of finches in the population increased, and the smaller-beaked finches were more successful in the drier environment.

b. The total number of finches in the population increased, and the larger-beaked finches were more successful in the drier environment.

c. The total number of finches in the population decreased, and the smaller-beaked finches were more successful in the drier environment.

d. The total number of finches in the population decreased, and the larger-beaked finches were more successful in the drier environment.

d. The total number of finches in the population decreased, and the larger-beaked finches were more successful in the drier environment.

Explanation:

Due to the effects of droughts that occurred in 1977, there were changes in the size and composition of the population of finches from the year 1976 to the year 1978.

Hence, the graph clearly depicts that the total number of finches in the population decreased, while the larger-beaked finches were more successful in the drier environment.
