Task: Answer the multiple choice question.
Query: Which drug has a 0.155\% 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: CCNC(=S)NNC(=O)c1ccc2ncccc2c1
b: COC(=O)c1cc2n(n1)CCN(Cc1ccccc1Cl)C2=O
c: COc1cc(C)ccc1S(=O)(=O)NC1CC(C)(C)NC(C)(C)C1
d: OCCNCCc1c[nH]c2ccc(OCc3ccccc3)cc12
Answer: b. COC(=O)c1cc2n(n1)CCN(Cc1ccccc1Cl)C2=O
