Error in morning CFAI mock exam?

Maybe I am missing something. Question 118 states the correct answer is B, but then explains how C should be correct as the market portfolio is perfectly positively correlated with other portfolios on the CML. Did anyone else run into this?

Yea I saw that too, checked the errata and it wasn’t mentioned; however, I’m pretty sure it’s supposed to be C.

C is right

C seems right. They should post it in the errata sometime soon. I wonder if this happens on the exam as well.
