According to the traditional examination rule for descriptive geographical…

Concept

Articles are determiners. ‘A’ and ‘an’ introduce a nonspecific singular count noun, while ‘the’ marks an identifiable referent or belongs to an established conventional name.

Traditional examination grammar also uses ‘the’ with certain descriptive geographical names, treating ‘Punjab’ as ‘the land of five rivers.’

Application

1. Read the stem under the traditional geographical-name convention stated in the question.

2. Under that convention, ‘Punjab’ is treated as a descriptive geographical name derived from the idea of five rivers.

3. The definite article is therefore inserted before the name, producing ‘the Punjab.’

Cross-check and contrast

• ‘a’ is licensed by a nonspecific singular count noun beginning with a consonant sound, such as ‘a state.’

• ‘an’ is licensed by a nonspecific singular count noun beginning with a vowel sound, such as ‘an area.’

• ‘the’ is licensed here by the traditional descriptive-geographical-name convention.

• ‘More than one of the above’ would require at least two article forms to satisfy the same blank.

• ‘None of the above’ would require a zero-article construction under the convention specified in the stem.

Contemporary general English often omits the article when the modern Indian state is meant. This source item, however, follows the traditional examination convention, and the BPSC final answer key confirms that intended reading.

Result

The sentence is completed as ‘He lives in the Punjab, a state of India.’ The accepted value is ‘the.’
