Task: Answer the multiple choice question.
Query: Which drug has a -6.253\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. CSCCC(NC(=O)c1ccccc1)C(=O)OCC(=O)c1ccc[nH]1
b. O=C(N/N=C/c1ccco1)c1cc([N+](=O)[O-])cc([N+](=O)[O-])c1
c. CCOC(=O)C1=C(C)NC(=O)N(C(C)=O)C1c1ccc(Cl)cc1
d. Oc1ccccc1CN1CCCC(N2CCc3ccccc3C2)C1
Answer: c. CCOC(=O)C1=C(C)NC(=O)N(C(C)=O)C1c1ccc(Cl)cc1
