“Rich gifts wax poor when givers prove unkind”?

After Polonius tells Ophelia to stop seeing Hamlet, and she obeys, why does Ophelia tell Hamlet (in 3.1), “Rich gifts wax poor when givers prove unkind”? (Hasn't SHE been unkind to Hamlet by obeying Dad, instead of honoring her heart and prince, who may be her future king?)

A
She believes her father,
that Hamlet only wrote her sweet letters
to take advantage of her sexually. (1.3)
She thinks Hamlet unkind, because she believes Dad.

B
He frightened her when he visited her
unannounced with doublet unbraced
& stockings fouled. (2.1)
He was unkind to frighten her like that.

C
He just claimed he "never gave [her] aught,"
(3.1) which she knows to be untrue, because
she knows he gave her the letters.
He was unkind to lie.

D
Some combination of the above
or OTHER (please comment)
