Task: Answer the multiple-choice question.
Question: Which compound has a 9.176\% 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 other words.
Options:
a: CCOC(=O)/C(=C/C=C1\Sc2cc(OCC)c(OCC)cc2N1CC)C(C)=O
b: COc1cc(C(C)=O)ccc1Oc1ncccn1
c: CCN(CC)c1ncc(C#N)c(N)n1
d: COc1ccc(/C(N)=N/OC(=O)CCCN2C(=O)c3ccccc3C2=O)cc1OC
Answer: a. CCOC(=O)/C(=C/C=C1\Sc2cc(OCC)c(OCC)cc2N1CC)C(C)=O
