Task: Answer the multiple-choice question.
Question: Which drug exhibits a 2.177% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) COc1cccc(C(C)NC(=O)c2c(F)cccc2Cl)c1
b) Cc1cc(N2CCN(C)CC2)nc2ccc(NC(=S)NCc3cccs3)cc12
c) COCCOC(=O)c1c(C)oc2ccc(OCC=C(C)C)cc12
d) Cn1c(=O)c2c(nc(SCC(=O)N3CCOCC3)n2C)n(C)c1=O
Answer: c. COCCOC(=O)c1c(C)oc2ccc(OCC=C(C)C)cc12
