A critique that centers on how the writer says what he says is an analysis. Option B is correct.
Critique is a method of disciplined, systematic study of a written or oral discourse. Although critique is commonly understood as fault finding and negative judgment, it can also involve merit recognition, and in the philosophical tradition it also means a methodical practice of doubt.
The term critique derives, via French, from Ancient Greek meaning "the faculty of judgment", that is, discerning the value of persons or things.
