Problem statement: Answer the multiple choice question.
Query: Which compound has a 8.255\% 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(O)/C=C/C(=O)N1CCN(c2ccccc2F)CC1
b: O=C(CSc1nc2[nH]c(=O)cc(O)c2s1)Nc1cccc(Br)c1
c: CCN(CC)CCN1C(=O)C(=O)/C(=C(/O)c2ccc3c(c2)CC(C)O3)C1c1ccc(OC)cc1
d: CS(=O)c1nc(-c2ccc(Br)cc2)cc(-c2ccccc2)c1C#N
e: CC(NC(=O)c1ccccc1Cl)c1ccc(-n2ccnc2)cc1
Answer: a. O=C(O)/C=C/C(=O)N1CCN(c2ccccc2F)CC1
