Task: Answer the multiple choice question.
Question: Which drug exhibits a -5.729\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a Cc1cc(OCC(=O)N[C@@H](Cc2c[nH]c3ccccc23)C(=O)O)c2c(C)c(C)c(=O)oc2c1
b CC(NC(=O)CSc1nc2c(cc1C#N)CN(C)CC2)c1ccccc1
c O=C1/C(=C/c2cccc([N+](=O)[O-])c2)CSc2ccc(Cl)cc21
d CCOC(=O)c1ccc(N2CN(CCc3ccccc3)CNC2=S)cc1
Answer: a. Cc1cc(OCC(=O)N[C@@H](Cc2c[nH]c3ccccc23)C(=O)O)c2c(C)c(C)c(=O)oc2c1
