Which of the following authors wrote in the naturalistic style?

A) Rudyard Kipling

B) Charles Dickens

C) Thomas Hardy

D) Charlotte Bronte

The answer is C. Thomas hardy

One thing that distinguishes naturalistic style with others is the use of logic and scientific method in portraying a certain fiction.

In his book Tess of the d'Urbervilles for example, we can see Thomas Hardy consistently taking supernatural factors out of the account and favoring scientific explanations

That would be Thomas Hardy.
