Hellen, CFA, develops marketing materials for an investment fund she founded four years ago. The materials show the four-year, three-year, two-year and one-year returns for the fund. Additionally, the footnote stating in small print reading ‘Past performance does not guarantee future returns’. In the footnote or disclosure, he does not claim compliance with the GIPS standards. A separate sheet is also included showing the fund's most recent semiannual and quarterly returns, which notes that those returns have been neither audited nor verified. Based on the information above, did Hellen most likely violate any Codes and Standards? A Yes, because he did not adhere to the Global Investment Performance Standards B No C Yes, because he included unaudited and unverified results 您好，老师，这个题麻烦给解析下
