As the principal in a real estate venture, Oni Erobo, CFA, faces a situation where increased costs of essential materials in the final month of construction lower the ROI below the Limited Partners' expected 35%. The cost escalation, however, remains within the 15% budget excess limit. Erobo chooses not to inform the Limited Partners about this. Has Erobo potentially breached the CFA Institute's Code of Ethics and Standards of Professional Conduct?

选项：

A.No, he acted within the set guidelines.

B.Yes, because the final ROI was less than the Partners had anticipated.

C.Yes, due to his lack of communication about the cost escalation.

解释：

Option A is correct. Erobo adhered to the agreed standards by not exceeding the 15% budget variance, and hence, was not obligated to report the minor cost increase in lighting fixtures. His decision not to inform the Limited Partners about the increase, which did not breach the preset budget cap, aligns with the Code and Standards.
