In Yim V J's Fashion Accessories, Inc

In Yim v. J's Fashion Accessories, Inc., where J's Fashion sued Yim for failing to pay for goods he bought under the name Ho Tae and Yim denied liability on the grounds that he had been acting as an agent for Hosung Enterprise, Inc which also did business under the name Ho Tae, the courts held that Yim was liable because:

A) the duty to disclose the principal is on the agent and Yim did not disclose Hosung Enterprise, Inc. as the principal
B) the duty to disclose the principal is on the third party and J's Fashion did not disclose Hosung Enterprise, Inc. as the principal
C) Hosung Enterprise, Inc. was a limited liability company and so could not be held liable
D) Yim made the contract without identifying Hosung Enterprise, Inc. as the agent
E) Yim unlawfully disclosed Hosung Enterprise, Inc. as the principal
