The DNIC has three digits to identify the country (one to identify a zone and two to identify the country within the zone) and one to identify the PDN (allowing only ten in each country).

Agree @Karthika.

The NTN identifies the exact network device (DTE, data terminal equipment) in the packet-switched network (PSN) and is often provided as an NUA. There are no rules to the structure of the NTN.

The first four digits of the international data number, the three digits that may represent the data country code, and the 1-digit network code, 1, the network digit.

For suppose.

The DNIC no of the country Germany: 262 2 (packet switched data service).

Here 262 represents data country code & last single digit "2"represents the netwrok digit (packet switched data service) -name of the n/w to which DNIC is located.

In the DNIC, the first four digits of the international data number, the three digits that may represent the data country code, and the 1-digit network code, i.e, the network digit.

The address is made up of the international data number (IDN), which consists of two fields: the 4 digit data network identification code (DNIC) and the (up to) 10 digit national terminal number (NTN). SO, the right answer is 4 digits (option B).
