Task: Answer the multiple choice question.
Query: Which compound has a 3.700\% 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) COc1ccc(-c2cc3cc(-c4cc(OC)c(OC)c(OC)c4)ccc3o2)cc1
(b) CCCCc1c(C)c2ccc(OCC(C)=O)cc2oc1=O
(c) C=CCN(C(=O)Cn1ncc2c1-c1cc(C)ccc1OC2)c1ccccc1
(d) COc1ccc2oc(=O)c(/C(N)=N/NC(=O)c3ccncc3)cc2c1
(e) Clc1ccc(Cn2cc(Br)cn2)cc1Cl
Answer: b. CCCCc1c(C)c2ccc(OCC(C)=O)cc2oc1=O
