Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.122\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CN(C)Cc1c(O)ccc2oc(Cc3ccccc3)cc12
[b] CN(C)C1=NCCN1CCCCc1ccccc1
[c] CN1C2C=C(N(C(=O)c3ccc(Cl)cc3)c3ccccc3)CC1CC2.Cl
[d] Cc1oc(-c2ccccc2Cl)nc1CS(=O)(=O)CC(=O)N1CCOCC1
Answer: b. CN(C)C1=NCCN1CCCCc1ccccc1
