| (c) Class D | (3) Large Organizations |
| (d) Class E | (4) Midsize Organizations |
Answer: D
The correct matching is (a)-3, (b)-4, (c)-1, (d)-2.
- Class A (first octet 1-126): very large networks, for large organisations.
- Class B (128-191): medium-sized networks, for midsize organisations.
- Class D (224-239): multicast addresses.

Option A makes Class D reserved and Class E multicast, which reverses them, and options B and C misplace Class A as well.
