Option C seems like a good choice too. Using the OOBM ports could provide an alternative path for the keepalive link, adding another layer of redundancy.
I think option B is the correct answer. A dedicated link on port 1/1/48 seems the most logical way to protect the aggregation layer in case the VSXISL fails.
