Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.119\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: C=CCc1c(C)nc2c(C)cccc2c1SC(=N)N.Cl
b: COc1cc(C2C(C(=O)c3ccc(C)o3)=C(O)C(=O)N2CCc2ccccc2)ccc1O
c: CC(C)OC(=O)NC(c1ccccc1)C(Cl)(Cl)Cl
d: CCNS(=O)(=O)c1cc(Br)ccc1OC
e: CCC(=O)N1CCc2cc(Br)cc(S(=O)(=O)CCC(=O)NCCOC)c21
Answer: b. COc1cc(C2C(C(=O)c3ccc(C)o3)=C(O)C(=O)N2CCc2ccccc2)ccc1O
