Task: Answer the multiple choice question.
Query: Which drug exhibits a 1.679\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) O=C(c1cc2c(s1)-c1ccccc1S(=O)(=O)C2)N1CCN(Cc2ccccc2)CC1
b) CCN(CC)c1nc(Nc2ccccc2)nc(Oc2ccc(=O)n(C)n2)n1
c) O=C(Nc1ccc2c(c1)OCO2)Nc1ccc(Br)cn1
d) Cc1cccc(NC(=O)c2ccc3ccccc3n2)c1C
e) Cc1nonc1OCCNc1ccc([N+](=O)[O-])c2cccnc12
Answer: c. O=C(Nc1ccc2c(c1)OCO2)Nc1ccc(Br)cn1
