Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -3.987% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Cc1cccc(NC(=S)N2CCN(c3ccccn3)CC2)c1
b: CCOc1cc(C2C3=C(CC(C)(C)CC3=O)N(CCOC)C3=C2C(=O)CC(C)(C)C3)ccc1O
c: CC1CCc2sc(C(=O)OCC(N)=O)cc2C1
Answer: b. CCOc1cc(C2C3=C(CC(C)(C)CC3=O)N(CCOC)C3=C2C(=O)CC(C)(C)C3)ccc1O
