Her task was, in part, to value the physical assets owned by a URL subsidiary that the URL management team wished to convince the board of directors to sell. The folks at URL are very sociable. Which of the following situations might endanger Maya's objectivity and$/$or integrity?

On Maya's birthday, URL gave her a birthday cake and a six$-$pack of beer produced by a microbrewery that operated by a URL subsidiary.

During yet another long string of meetings between Maya's team and URL employees, URL ordered in a bunch of pizza for everyone to share.

Also on her birthday, URL's CEO, Tisha, gave Maya a beautiful necklace worth $$1,000.$

At the end of a long day of meetings, Maya and her team went to a local sandwich restaurant with a few URL employees to grab a bite before they all went back to work. Sam, the senior URL employee at the meal paid for everyone's meals with her personal credit card without telling anyone until everyone was ready to leave.
