The question did not say that the vCenters were at different sites, so multi-site is not required. It is common where VDI is being used, to have more than one vCenter at the same site (1 or more for VDI and one for servers) The first SSO that is installed will be basic in any case. More than one vCenter and inventory servers can be attached to it. Acording to the VMware doc:
vCenter Server instances in linked mode can be connected to different physical Single Sign-On servers, but must be connected to a single logical Single Sign-On server. A single logical Single Sign-On server can take any of the following forms.
■ A single physical Single Sign-On server.
■ Two nodes of a cluster. Effectively this is the same as a single physical Single Sign-On server because the nodes use the same Single Sign-On database.
■ Two nodes in multisite mode.

I found this in the 5.5 Documentation center. If it is to be taken literally, then Multi-site is not allowed which would be a huge problem for SRM. So I think it means an SSO instance/domain, what-ever is the correct term as my previous post specifies.
“Make sure that all vCenter Servers in a Linked Mode group are registered to the same vCenter Single Sign-On server.”

I would have to say option c:
it clearly states that unless multiple sites need it than all other is basic single sign on.

@Elizabeth, the question mentions 2 servers in linked mode so the answer is B.

The important information is that both vCenter are configured in linked mode hence you will need to use multiple SSO instances.
There are two types of multiple SSO instances: on the same location or on different locations. But when you set up the SSO instances on different locations, they must use linked mode and be on the same AD / identity source domain.
