Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.826\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) COc1ccc(CNc2nc3nc(-c4ccccc4)cc(=O)n3[nH]2)cc1OC
b.) O=C(N/N=C/c1cccc(Br)c1)c1ccc(Cn2cc(Br)cn2)o1
c.) CCOc1ccc(CCNC(=O)CCc2nc(-c3ccc(C)cc3)no2)cc1OCC
d.) CC(=O)c1ccc(NC(=O)c2noc(C(C)C)c2[N+](=O)[O-])cc1
Answer: c. CCOc1ccc(CCNC(=O)CCc2nc(-c3ccc(C)cc3)no2)cc1OCC
