Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.392\% 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: CCCN(CC(=O)Nc1ccc(F)c(F)c1F)C(=O)CCc1nc2ccccc2c(=O)[nH]1
b: O=C(CCS(=O)(=O)c1ccccc1)Nc1ccc(-c2nc3ccccc3s2)cc1
c: COc1ccc(CNC(=O)c2ccc(NC(=O)C3=CSCCO3)cc2)cc1
d: COc1cccc(NC(=O)C2C3C=CC4(O3)C2C(=O)N(CCCN2CCCC(C)C2)C4C(=O)NC2CCCCC2C)c1
Answer: b. O=C(CCS(=O)(=O)c1ccccc1)Nc1ccc(-c2nc3ccccc3s2)cc1
