Complete answer:
Let us study the options to find the correct answer:
Option A: This book is on facing the difficulties arrived by the increase in population size and geometric progression increment as well as the increase in arithmetic progression of food production, so this shows the difference between the fame and famine and this was the book which was written by T. R. Malthus on the population. Therefore, this is the correct answer.

Option B: As mathematics is a different subject and the author T.R. Malthus was not a mathematician so he has not written any mathematics book. Therefore, this is an incorrect answer.

Option C: Geography is a subject which is related to the discoveries of earth or discoveries of India, with this aspect he is not the writer of any geography book. Therefore, this is an incorrect answer.

Option D: Genetics is the aspect that is a branch of biology and related to the study of genes, genetic regulation, etc. therefore this is an incorrect answer.
