Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.606\% 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 O=C1CC(C(=O)Nc2ccccc2)N=C(N2CCCCC2)N1
b COc1cccc(-c2sc3ccc(OC)cc3c2C#CC2(O)CCCCC2)c1
c COc1ccc(Cn2c(CCC(=O)Nc3ccc(C)cc3)nc3cccnc32)cc1
d COc1cccc(NC(=O)CSc2nc3c(oc4ccccc43)c(=O)n2C)c1
Answer: a. O=C1CC(C(=O)Nc2ccccc2)N=C(N2CCCCC2)N1
