Which mailing address to use for disputing a California Franchise Tax Board 5818 Notice?

I just got an FTB 5818 Notice saying that I don't have Health Insurance.

I am planning to dispute it by sending in my 1095-B.

Question: Which mailing address should I be using:

a: 

Franchise Tax Board
PO Box 942840
Sacramento CA [removed]

or

b:

Franchise Tax Board
PO Box 942867
Sacramento CA [removed]

Thanks
