Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -42.333% hERG inhibition at a concentration of 10uM?
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(/C=C/c1cccnc1)c1ccc([N+](=O)[O-])cc1
b Cc1ccc(C)c(N=Cc2ccc(-c3ccc([N+](=O)[O-])cc3)o2)c1
c CCCCNC(=O)CSc1nc2ccccc2n1S(=O)(=O)c1ccc(Cl)cc1
d CCC(CC)C(=O)N(CCc1ccc(OC)cc1)Cc1nc2ccccc2c(=O)[nH]1
e COc1ccc(C(=O)Nc2cc3c(cc2N2CCOCC2)n(C)c(=O)n3C)cc1OC
Answer: a. O=C(/C=C/c1cccnc1)c1ccc([N+](=O)[O-])cc1
