Which of these quotations from the poem contains a coordinating conjunction?
a. “And sometimes they sacrificed to the old stone gods,”
b. “How the monster relished his savage war / On the Danes,”
c. “Remember, / Hrothgar, O knowing king …”
d. “Then when the darkness had dropped, Grendel…”
A. "And sometimes they sacrificed to the old stone gods,"
There are seven coordinating conjunctions: for, and, nor, but, or, yet, so. Choice A is the only one that contains any of those, therefore it is correct.
