Fill in the blanks with the most appropriate option:-

Stalin was _________ of poor parents.

born

The most appropriate option to fill in the blanks is born.

The word "born" is the past participle of the verb "to bear", which means to bring forth a child. In the context of the sentence, "Stalin was born of poor parents", Stalin was brought forth by his parents. The other options are not as appropriate.

• Borne can be used as a past participle of the verb "to bear", but it is more commonly used as an adjective that means "carried". This does not make sense in the context of the sentence, as Stalin was not carried by his parents.
• Birth can be used as a noun that means the act of being born. This does not make sense in the context of the sentence, as Stalin was not the act of being born.
• Borned is not a word.
