I might be wrong, but I think the error is the way they spelled okay. When you are writing in an essay or any other forms of writing, I think you’re supposed to spell the word out instead of abbreviating it.
I hope this helps :)
The correct answr is D. The spider scurried under the kitchen cabinet.
"Under" is the preposition here which signifies the logical relationship between two objects, the spider and the kitchen cabinet.
Under signifies how these two objects are connected to each other.
D. It does not have a verb and it is not a complete thought
So your answer would be paternal since it means father
made of deeds of great valor or requiring superhuman courage.
