Task: Answer the multiple-choice question.
Question: Which drug exhibits a 3.606\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. COc1ccc(N2CCN(C(c3cc(OC)ccc3OC)c3nnnn3CC3CCCO3)CC2)cc1.Cl
b. O=C1C2C3C=CC(C3)C2C(=O)N1CCCCN1C(=O)C2C3C=CC(C3)C2C1=O
c. O=C(OC1CCOC1=O)c1ccc(CO)cc1
d. CC(C)c1ccc2[nH]c(O)c(N=NC(=O)c3cccc(S(=O)(=O)Nc4ccccc4Cl)c3)c2c1
Answer: b. O=C1C2C3C=CC(C3)C2C(=O)N1CCCCN1C(=O)C2C3C=CC(C3)C2C1=O
