C. Gigantic
Gigantic is the correct spelling
The correct punctuation and subject-verb agreement for the sentence would be "A newly uncovered Viking fortress on Zealand, Denmark's largest island, is shaped like a ring and may have served as a military training ground for Viking attacks on England."
<h3>The correct punctuation for the sentence</h3>
The phrase "Denmark's largest island" functions as an appositive in the sentence, which means it renames the noun "Zealand," providing more information about it. Appositives such as this one, explaining a term in the sentence, should be set off by commas.
<h3>Subject-verb agreement</h3>
A verb should agree with the subject when it comes to being singular or plural. In the sentence, the subject "fortress" is singular, so there is no need to use the plural verb "are". The correct verb would be "is".

"Neither as a boy nor as a man was he a toady, but from early youth was by nature attracted to people of high station as a fly is drawn to the light, assimilating their ways and views of life and establishing friendly relations with them. " <em>Leo Tolstoy's The Death Of Ivan Ilyich </em>
To me this seems like the answer, because it says that from early youth he had always admired those of a higher society. I am not an expert but this sentence kind of stuck out to me.
