Logical predication + Rhetorical construction

This sentence awkwardly presents two phrases intended to
modify Beatrix Potter and loses the clarity and logic of the meaning. In
the original sentence, these modifiers sound choppy and create too much
separation between the subject, Beatrix Potter, and the verb capitalized
Beginning the sentence with in her book illustrations and following
that phrase with the relative clause which she carefully coordinated with
her narratives allows the subject, Beatrix Potter, to be united with
the verb, capitalized, for a stronger main clause.

A     The modifying
elements are poorly placed and leave the subject too far from the verb

B      Phrase carefully
coordinating ... illogically modifies the noun that immediately precedes it
(book illustrations); Potter, not the illustrations, did the
coordinating; awkward and unclear

C     Correct. The correct placement of the
modifying elements makes this sentence easier to understand; the use of which
clearly links the two elements.

D     Carefully
coordinated ... absurdly modifies Beatrix Potter rather than her
illustrations

E      Them cannot refer to book illustrations
because the plural noun is the object of the preposition in; the relationships
among the parts of the sentence are unclear
