Refer to the exhibit. An architect must design an IP addressing scheme for a multisite network connected via a WAN transit. The campus site must accommodate12,000 devices, and the branch sites must accommodate 1,000 devices. Which address scheme optimizes network device resources, contains convergence events to the different blocks of the network, and ensures the network's future growth?

A. Campus: 10.0.0.0/18 Branch1: 10.0.192.0/21 Branch2: 10.0.200.0/21 B. Campus: 10.0.0.0/16 Branch1: 10.255.0.0/20 Branch2: 10.255.16.0/20 C. Campus: 10.0.0.0/10 Branch1: 10.64.0.0/10 Branch2: 10.128.0.0/10 D. Campus: 10.0.0.0/20 Branch1: 10.0.64.0/21 Branch2: 10.0.128.0/21
