D. writing that explains a specific topic without showing the author's opinion or feelings.
The writer is Dickens so the S belong to the surname. There are 2 possible forms to express a possesive case here.
The most common one would be option D <span>Dickens’. A general rule might be applied where because the noun ends in S we can only add the apostrophe, However, a second possibility is also allowed, It is option B </span><span>Dickens’s. This option might depend on pronunciation that is why it is not so commonly used. </span>
