Task: Answer the multiple choice question.
Question: Which compound has a 4.850\% 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. CC1(c2nnc(-c3ccc(F)cc3)o2)CC(c2ccc(F)cc2)=NO1
b. O=C(CSc1nncn1-c1ccccc1F)NC1CCCCC1
c. COc1ccc(C(CNC(=O)c2ccc(OCc3c(C)noc3C)cc2)N2CCCC2)cc1
d. CC(C)Cn1c(-c2ccco2)n[nH]c1=S
Answer: b. O=C(CSc1nncn1-c1ccccc1F)NC1CCCCC1
