Task: Answer the multiple choice question.
Query: Which compound exhibits a -18.921\% 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. C/C(=N/NC(=O)c1nnn(-c2nonc2N)c1-c1ccccc1)c1ccc2c(c1)OCO2
b. O=C(NC1CC1)C1=NOC(CNc2ncc(C(F)(F)F)cc2Cl)C1
c. Cc1nnc(SCc2ccccc2C#N)n1-c1ccccc1
d. COc1ccc(NC(=O)C2=CC(c3cccs3)=NS(=O)(=O)N2C)cc1OC
Answer: b. O=C(NC1CC1)C1=NOC(CNc2ncc(C(F)(F)F)cc2Cl)C1
