Task: Answer the multiple choice question.
Query: Which compound exhibits a 11.017\% 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 other words.
Options:
(a) Cc1cccc(-[n+]2c(-c3cccc(Br)c3)[nH]c3nc4ccccc4nc32)c1
(b) CCOC(=O)/C(C#N)=C/C=C1/C=CC=CN1C
(c) CCOc1ccc(CCNC(=O)CN(C)S(=O)(=O)c2cccc3nsnc23)cc1OCC
(d) COc1cccc(-n2c(=O)[nH]cc(C(=O)Nc3ccc(NC(C)=O)cc3)c2=O)c1
(e) COC(=O)C1C(c2ccccc2)C(C(=O)N2CCOCC2)C1c1ccccc1
Answer: b. CCOC(=O)/C(C#N)=C/C=C1/C=CC=CN1C
