Which sentence uses a semicolon correctly

sentence no.1

Explanation:

4

Explanation:

Semi colons are used for 2 independent sentences which are related.

Option 1 is WRONG because the words after the semicolon is not an independent sentence. If a "colon" was used here, it would be correct.

Option 2 is WRONG because of the same reasoning above, but using a "colon" here would still be wrong.

Option 3 is WRONG of the same reasoning for option 2.

Option 4 is CORRECT because it has 2 independent sentences combined with a semicolon which the topics are also related to eachother.

martians or other types of aliens represent a unique fear as opposed to zombies. vampires and other types of monsters.   in most sci-fi stories, aliens come from other worlds and have different or more advanced technology.   abductions and experimentation on human bodies that involve these technologies, or the use of these technologies against human beings and the use of unknown "powers", are a type of fear that's different from that of other types of monsters.
