Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.590\% 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. O=C(Nc1ccc2oc(-c3cccc(F)c3)nc2c1)c1ccccc1F
b. Cc1ccc(CNC(=O)C2CCN(C(=O)Nc3ccccc3)CC2)cc1
c. COc1ccc(NC(=O)c2cc(-c3ccco3)nc3ccccc23)cn1
d. O/N=C1\CCCc2oc3c(c21)CCCC3
Answer: a. O=C(Nc1ccc2oc(-c3cccc(F)c3)nc2c1)c1ccccc1F
