Task: Answer the multiple choice question.
Question: Which drug has a 1.987\% 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 additional words.
Options:
a CC(C)NC(=O)c1ccccc1NC(=O)/C=C/c1ccc([N+](=O)[O-])cc1
b Cc1cc(C)c(C#N)c(SCC(=O)N2CCN(Cc3ccccc3)CC2)n1
c Cc1cnc(NC(=O)c2ccc3c(c2)C(=O)N(Cc2cccnc2)C3=O)s1
d O=C(Cc1ccccc1[N+](=O)[O-])NNC(=O)Nc1ccc2c(c1)OCO2
e CN(C)c1ccnc(SCc2ccccc2Cl)c1C#N
Answer: e. CN(C)c1ccnc(SCc2ccccc2Cl)c1C#N
