In this article, is explicitly said that the domain separation level is "Basic": https://docs.servicenow.com/bundle/washingtondc-it-business-management/page/product/project-portfolio-suite-with-financials/concept/domain-separation-project-portfolio-financials.html In this article, it explains what the basic level means, but uses the word "customer" instead of "tenant": https://docs.servicenow.com/bundle/utah-platform-security/page/administer/company-and-domain-separation/reference/bp-domain-levels.html

Correct answer is B or D. I can't tell from the documentation. https://docs.servicenow.com/ja-JP/bundle/utah-it-business-management/page/product/project-portfolio-suite-with-financials/concept/domain-separation-project-portfolio-financials.html

B is correct

I going to disagree with D. Project Portfolio Management is BASIC as per https://docs.servicenow.com/bundle/sandiego-it-business-management/page/product/service-portfolio-management2/concept/domain-separation-SPM2.html Basic is defined by https://docs.servicenow.com/en-US/bundle/utah-platform-security/page/administer/company-and-domain-separation/reference/bp-domain-levels.html under the header "Customer data management" Tenant and customer are used interchangeably in this document https://docs.servicenow.com/bundle/sandiego-it-business-management/page/product/service-portfolio-management2/concept/domain-separation-SPM2.html

D is correct
