SSL certificate to secure multiple domains hosted at winhost

I have a primary account, with primary domain at winhost, lets call it acme.com.

I also have multiple subdomains, lets say marketplace.acme.com, otherapp.acme.com

In addition, I am also having domain pointers under the same account, lets say codehub.net, bumblebee.co.uk, etc.

So in the above example, I've given 5 different domains;

When I get the SSL cert, can
a) one cert cover all domains, subdomains, and domain pointers,
b) do I need 5 separate certs for each domain ?
c) something else altogether, what do you suggest?

And the follow up question is does winhost allow multiple SSL certs under the one account ?

 

That answers it, thanks. I guess it should be a FAQ somewhere on your knowledge base, someone else will repeat the question !
