Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 9.055\% human ether-à-go-go related gene (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: Oc1ccccc1/C=N/N1CCN(c2ccccn2)CC1
b: O=S(=O)(N/N=C/c1ccc(N2CCOCC2)cc1)c1ccc(Br)cc1
c: O=C(N/N=C/C1CCCCC1)c1ccccn1
d: CCCCC1=CC2=C(c3ccco3)C(=O)C(C)(OC(=O)c3ccc(OC)cc3)C(=O)C2=CN1CCOC
Answer: a. Oc1ccccc1/C=N/N1CCN(c2ccccn2)CC1
