  Consult your power of 2 chart to find the target subnet. For R7, the host requirement maps directly to a /22 subnet. Because option C is the only choice matching that prefix, theres your answer in no more than 15 secs

  Calculating R7 reveals the answer. With 10% growth it makes less than 1024 hosts. That means /22 subnet which is 255.255.252.0.
