Task: Answer the multiple choice question.
Question: Which drug has a 4.299\% 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.) COc1ccc(NC(=O)CSc2nccc(C)n2)cc1
b.) COc1ccc(OC)c(C2C(C#N)=C(N)Oc3c2c(C)nn3-c2ccc(C)cc2)c1
c.) O=C(CCCN1C(=O)/C(=C/c2cccs2)SC1=S)Nc1ccc(C(=O)O)cc1
d.) CC1=NN(c2cccc(Cl)c2)C(=O)C12CC(C)=C(C)CS2
Answer: b. COc1ccc(OC)c(C2C(C#N)=C(N)Oc3c2c(C)nn3-c2ccc(C)cc2)c1
