Task: Answer the multiple-choice question.
Question: Which drug exhibits a 1.913\% 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(CNC(=O)C2CCN(c3nnc(N4CCCC4=O)s3)CC2)cc1
b.) CC#C[C@]1(O)CC[C@H]2[C@@H]3CCC4=CC(=O)CCC4=C3[C@@H](c3ccc(N(C)C)cc3)C[C@@]21C
c.) COc1ccc(OC)c(NC(=O)C2CCN(c3cc(-c4ccccc4)nc4ncnn34)CC2)c1
d.) CCc1ccccc1NC(=O)CN(C)C(=O)Cn1ncc(Cl)c(Cl)c1=O
Answer: a. COc1ccc(CNC(=O)C2CCN(c3nnc(N4CCCC4=O)s3)CC2)cc1
