Task: Answer the multiple-choice question.
Query: Which compound exhibits a -1.207\% 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(c1ccccc1F)N1CCN(C(=O)C(c2ccccc2)c2ccccc2)CC1
[b] O=C(O)CCC(=O)N1CCN(c2ccc(C(=O)c3ccc(F)cc3)cc2)CC1
[c] O=C1/C(=C\c2ccccc2)CCc2c1[nH]c1ccccc21
[d] Cc1ccc(S(=O)(=O)NNC(=O)Cc2cccn2C)cc1
[e] O=C(NC1CCCCC1)C(c1cccs1)N(C(=O)c1ccccn1)c1ccccc1
Answer: b. O=C(O)CCC(=O)N1CCN(c2ccc(C(=O)c3ccc(F)cc3)cc2)CC1
