Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.432\% 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 CC(=O)c1ccc(Nc2ccc(-c3ccccc3C)nn2)cc1
b O=C(Cn1cnc2ccccc21)NC(c1ccccc1)c1ccccc1
c Cn1c(-c2ccccc2)cnc1SCC(N)=O
d CCOC(=O)c1c(C)n(OCc2ccccc2)c2ccc3c(no[n+]3[O-])c12
Answer: b. O=C(Cn1cnc2ccccc21)NC(c1ccccc1)c1ccccc1
