Answer:

D. 19 bits are reserved for the network part of IP addresses on the Network

Explanation:

The /19, expresses in the CIDR (Classless Interdomain Routing) notation, how many bits are part of the address mask, which represent the network ID in the IPv4 address.

In this case, we have the first 19 bits set to “1”, which in decimal notation should be written as follows:

255.255.224.0
