Task: Answer the multiple-choice question.
Question: Which drug exhibits a 9.065\% 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 additional words.
Options:
a: CCc1noc(C)c1C(=O)OCC(=O)c1ccccc1OC
b: CCC(C)C1C(C#N)=C(N)Oc2n[nH]c(-c3ccccc3)c21
c: O=C(C1CC(=O)N(c2ccc(Cl)cc2)C1)N1CCOCC1
d: NNC(=O)c1ccc(Cn2cc(Br)c(N)n2)cc1
Answer: b. CCC(C)C1C(C#N)=C(N)Oc2n[nH]c(-c3ccccc3)c21
