Task: Answer the multiple-choice question.
Query: Which compound has a 7.181\% 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) O=C(CCCCCNC(=O)c1ccccc1)N/N=C/c1ccccc1O
(b) CCOC(=O)C1=C(N)OC2=C(C(=O)CCC2)C1c1ccccc1OCC
(c) Fc1ccc2c(-c3cccc(C(F)(F)F)c3)c(-c3ccccc3)ncc2c1
(d) O=C(c1ccc(S(=O)(=O)N2CCC(c3nc4ccccc4[nH]3)CC2)cc1)N1CCOCC1
(e) O=C(Nc1ccc(Cl)cc1)C(c1ccccc1)N(CCO)CCO
Answer: b. CCOC(=O)C1=C(N)OC2=C(C(=O)CCC2)C1c1ccccc1OCC
