Task: Answer the multiple-choice question.
Query: Which compound exhibits a 5.677\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) O=C(NCCO)c1cc(-c2cc(C(=O)NCCO)c3ccccc3n2)nc2ccccc12
(b) COc1ccc(CCNCc2csc3nc4ccccc4n23)cc1OC.Cl
(c) Cc1c(CC(=O)O)c(=O)oc2cc(OCc3ccc(F)cc3Cl)ccc12
(d) C/C(=N/O)c1ccc(Oc2cnccn2)cc1
(e) COCc1cc(C)nc(SCC(=O)Oc2ccc(Cl)cc2)c1C#N
Answer: a. O=C(NCCO)c1cc(-c2cc(C(=O)NCCO)c3ccccc3n2)nc2ccccc12
