Task: Answer the multiple choice question.
Query: Which drug has a -5.899\% human ether-à-go-go related gene (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: CN1C2=NCCN2C(=O)c2cc(Cl)ccc21
b: CCc1ccc(N(CC(=O)NC(C)(C)C)C(=O)CNC(=O)c2cccs2)cc1
c: COCCOC(=O)c1c(C)oc2ccc(O)c(CN3CCC(C)CC3)c12
d: O=C(CN1C(=O)NC2(CCCC2)C1=O)Oc1ccc2ccc(=O)oc2c1
Answer: c. COCCOC(=O)c1c(C)oc2ccc(O)c(CN3CCC(C)CC3)c12
