An RR calls his most important client to tell her that the Treasury bond in her account is losing money. She agrees to sell it at a $5,000 loss. The RR reassures her not to worry about the loss as her investment is guaranteed. Given the statement to the client, the RR

[A] behaved appropriately as Treasury securities are guaranteed by the U. S. government.
[B] behaved inappropriately as guaranteeing customers against a loss is a violation.
[C] should have also stated that the losses are guaranteed up to $10,000 only.
[D] is mistaken because no mention was made that the loss is recovered only if held to maturity.
