Explanation

For an online-only business, the web server is the sole channel through which revenue is generated and customers are served. A vulnerability to Distributed Denial of Service (DDoS) attacks directly threatens availability of the entire business - a successful DDoS can take the business completely offline. This is an existential availability risk. A slow back-office payment system (A) impacts operations but not customer access. SSO authentication failures (C) are disruptive but partial. Unpatched visitor WiFi (D) is a lower-tier network segment with minimal business-critical exposure. DDoS on the web server represents the highest impact, highest probability availability threat for an online-only operation.
