The correct answer is B. Load balanced 4vCPU with 8GB RAM on single availability zone. The requirements specify 8vCPU and 16GB RAM total, low inter-VM latency, horizontal scaling, 98.5% availability, and job splitting across VMs. Option B uses two load-balanced VMs (2 × 4vCPU = 8vCPU, 2 × 8GB = 16GB) within a single availability zone.

Explanation
The requirements specify 8vCPU and 16GB RAM total, low inter-VM latency, horizontal scaling, 98.5% availability, and job splitting across VMs. Option B uses two load-balanced VMs (2 × 4vCPU = 8vCPU, 2 × 8GB = 16GB) within a single availability zone. A single AZ minimizes inter-VM network latency since VMs are physically close. Load balancing provides horizontal scaling and supports splitting jobs. Multiple VMs meet the 98.5% availability target. Option A and C use only 2vCPU/4GB per VM which doesn't meet the compute requirement even combined. Option D is a single VM, so it cannot horizontally scale or split jobs, and is a single point of failure.
