The quotation that most effectively illustrates Marianne Dashwood's ability to persuade others of the rightness of her artistic judgments is:
(Choice B) “Their taste was strikingly alike. The same books, the same passages were idolized by each—or if any difference appeared, any objection arose, it lasted no longer than till the force of her arguments and the brightness of her eyes could be displayed.”
This choice highlights Marianne's persuasive skill and her influence over others, as it suggests that her passionate arguments and expressive demeanor can easily sway opinions in her favor.
