stuck please explain.

Consider a datagram network using 8-bit host addresses. Suppose a router uses longest prefix matching and has the following forwarding table: Prefix Match Interface 11 011 10 00 01003 Default 4 What is the associated range of destination addresses for the default interface? (Use binary notation.) Select one: O a. 01000000 through 01001011 O b. 01010000 through 01011111 O c. 01000000 through 01010101 O d. 00000000 through 00111111
