Problem statement: Answer the multiple choice question.
Question: Which drug has a 0.853\% 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 other words.
Options:
a CC(=O)OC[C@H]1O[C@@H](n2ccc(=O)[nH]c2=S)C(OC(C)=O)C1OC(C)=O
b COCCCN1C(=O)c2ccc(C(=O)NCc3ccco3)cc2C1=O
c CCOC(=O)CN1c2ccccc2NC(=O)CC1C
d O=C1/C(=C/c2ccc(N3CCOCC3)o2)SC(=Nc2ccccc2)N1CCc1c[nH]c2ccccc12
Answer: c. CCOC(=O)CN1c2ccccc2NC(=O)CC1C
