    Key concept: We want to block PORTS in a PARTICULAR (s) HOST.
    So in here I want to block ports at a HOST level (as opposed to at NETWORK level)
    This is achieved by a HOST-BASED-FIREWALL.
    In addition to that, A, C and D do not block ports at any level.

    A.A host-based intrusion prevention system – This does not block ports
    C.Antivirus update system – This does not block ports. Port would still be open for other types of illegal activities not containing a virus.
    D.A network-based intrusion detection system – This is at “network” level and would apply to ALL computers in the network, and not just on “computers that do credit card transactions”
    So the correct answer is:
    B- A host-based firewall is the only option that blocks ports at HOST level
    A host-based firewall is installed on a client system and is used to protect the client system from the activities of the user as well as from communication from the network or Internet.
