Task: Answer the multiple choice question.
Question: Which drug has a -27.215\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C(Cn1nnc(-c2ccccc2Cl)n1)N/N=C/c1ccc(-c2cccc(Cl)c2)o1
b CN(C)S(=O)(=O)c1cccc(NC(=O)COC(=O)CCOc2ccccc2)c1
c CCCCN(CCCC)C(=O)/C=C/c1cccc([N+](=O)[O-])c1
d Cc1c(C(=O)N2CCN(c3ccc([N+](=O)[O-])cc3)CC2)oc2ccccc12
Answer: c. CCCCN(CCCC)C(=O)/C=C/c1cccc([N+](=O)[O-])c1
