The correct answer is “superior to”.
The word “superior” means “better than” or “of higher quality than”. In the sentence “Our armed forces are superior to those of any other country in the world”, the word “superior” is used to compare the armed forces of the speaker’s country to the armed forces of other countries. The speaker is saying that the armed forces of their country are better than the armed forces of any other country.
The other options are incorrect because they do not make sense in the context of the sentence. The word “superior than” is not a grammatically correct phrase. The word “superior from” is not a commonly used phrase, and it does not make sense to compare something to “from” something else. The word “superior of” is also not a commonly used phrase, and it does not make sense to compare something to “of” something else.
In conclusion, the correct answer is “superior to”.
