[New Furniture] Kristin Purchased $2,000 Worth of Furniture from Solid

[New Furniture] Kristin purchased $2,000 worth of furniture from Solid Wood Furniture. Through an arrangement with Solid Wood, Kristin financed the purchase through a financing company called Let Us Help You. Twenty-nine days after the goods were delivered to her, Kristin had a disagreement with Let Us Help You regarding the amount of interest she would be required to pay. She notified Solid Wood on that day that she was rejecting the goods. Solid Wood claimed that she did not properly reject the furniture and also that she failed to act in good faith, an obligation imposed equally on all parties to a transaction. Kristin says that she properly rejected; that, although the UCC imposes no duty of good faith, she acted in good faith; and that, in any event, she had an absolute right to return the goods.
-Which statement is true regarding the claim of Solid Wood that Kristin failed to properly reject the goods?

A) Solid Wood is incorrect because under the UCC Kristin had 30 days in which to reject the goods.
B) Solid Wood is incorrect only if Kristin can establish that Let Us Help You miscalculated the amount of interest she owed.
C) Solid Wood is incorrect only if Kristin can show that the goods were overpriced.
D) Solid Wood is correct only if Solid Wood can show that the goods were priced at reasonable market value.
E) Solid Wood is correct.
