Task: Answer the multiple-choice question.
Query: Which drug has a 11.164\% 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 additional words.
Options:
a) CCOC(=O)C1CCN(/C=C2/C(=O)NC(=S)N(c3ccccc3F)C2=O)CC1
b) O=C(Nc1nccs1)c1ccc2c(c1)OCO2
c) CC1CCN(CC(O)COc2ccc(OCC(O)CN3CCC(C)CC3)cc2)CC1
d) Fc1cccc(-c2nn[nH]n2)c1
Answer: b. O=C(Nc1nccs1)c1ccc2c(c1)OCO2
