Great question. You're right—this is the part of the passage where we can figure out that the author likely believes that it's important that literary criticism employ skill and insight.
In stating that "deconstructionism has no overtones of skill or wisdom; it merely suggests demolition of an existing building," the author is implying that she has a negative view of deconstructionism and believes that literary criticism should employ skill and insight, which is what makes answer choice B correct.
I'm happy that you were so finely tuned in to this question. Keep up the great work, and as always, let us know if you have any questions!
