Problem statement: Answer the multiple choice question.
Query: Which drug has a -0.421\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) Cc1ccc(NC(=O)c2ccc(N3CCOCC3)c([N+](=O)[O-])c2)cc1S(=O)(=O)N1CCOCC1
b) O=C(NNC(=O)c1cc(F)c(F)cc1Cl)c1ccc(NS(=O)(=O)c2cccs2)cc1
c) O=C(N/N=C\c1ccc(Cl)s1)c1ccc(Cn2cccn2)o1
d) CCOC(=O)C1C(c2ccccc2)C(C(=O)OCC)C1c1ccccc1
e) CCNC(=O)C(=O)c1c(-c2ccccc2)[nH]c2ccccc12
Answer: a. Cc1ccc(NC(=O)c2ccc(N3CCOCC3)c([N+](=O)[O-])c2)cc1S(=O)(=O)N1CCOCC1
