Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 11.945\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: Oc1[nH]c(N=C2N=c3ccccc3=N2)c2ccccc12
b: CCN(C(=O)CN1CCN(c2ccccc2OC)CC1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
c: Cc1ccc(-n2c(SCc3nc4ccccc4c(=O)[nH]3)nnc2-c2ccccc2O)cc1
Answer: b. CCN(C(=O)CN1CCN(c2ccccc2OC)CC1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
