In the sentences given, you need to distinguish between proper nouns and common nouns.
Proper Nouns are specific names given to particular people, places, organizations, or sometimes things. They are always capitalized because they denote a unique entity.
Common Nouns are general names for a person, place, or thing in a class or group. Unlike proper nouns, they are not capitalized unless they begin a sentence.
Let's look at the sentences one by one:
i. "Pakistan is my country."
Proper Noun : Pakistan (It's a specific name of a country.)
Common Noun : country (It's a general name for a place.)
ii. "My sister's name is Mary."
Proper Noun : Mary (It's a specific name of a person.)
Common Noun : sister (It's a general term for a family member.)
iii. "I like chocolate ice-cream."
Proper Noun : None in this sentence.
Common Nouns : chocolate, ice-cream (Both are general terms for types of food.)
In summary:
Proper nouns include 'Pakistan' and 'Mary' as they identify specific entities and are capitalized.
Common nouns include words like 'country', 'sister', 'chocolate', and 'ice-cream' as they denote more general categories or types.
