Task: Answer the multiple-choice question.
Question: Which drug exhibits a 16.201\% 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.) O=C(COC(=O)c1ccccc1Br)Nc1ccc2[nH]c(=O)[nH]c2c1
b.) CC1CCCC(C2(O)C(=O)Nc3ccccc32)C1=O
c.) CCn1c(CNC(=O)c2cc(OC)c(OC)c(OC)c2)cc2cc(C)ccc21
d.) O=C(c1ccc(SCc2ccco2)c([N+](=O)[O-])c1)N1CCOCC1
Answer: b. CC1CCCC(C2(O)C(=O)Nc3ccccc32)C1=O
