Explanation

Basic Azure Load Balancer is correct because it supports distributing traffic across virtual machines within the same availability set, satisfying the high availability requirement (health probes will reroute traffic away from a failed VM), and it is offered at no additional cost - directly addressing the cost minimization requirement.

Why the others are wrong:

• C (Standard Load Balancer): Also capable of the task, but incurs an hourly charge per rule and data processed. Since the VMs share an availability set, the free Basic tier is sufficient.
• A (Application Gateway): A Layer 7 (HTTP/HTTPS) load balancer with URL routing and SSL offload - more feature-rich but significantly more expensive, making it overkill for this scenario.
• B (Web Application Firewall): WAF is a security feature (typically an add-on to Application Gateway or Front Door), not a standalone traffic distribution solution. It cannot replace a load balancer.

Memory tip: Whenever an exam question mentions cost minimization + same availability set, reach for Basic Load Balancer - it's the "free tier" of Azure load balancing and is purpose-built for intra-availability-set HA scenarios. If the question mentions availability zones or cross-region, that's when Standard (or above) becomes necessary.
