Task: Answer the multiple choice question.
Query: Which compound exhibits a -6.454\% 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] O=C(NCC1CCN(Cc2ccccc2F)CC1)Nc1cccc(Br)c1
[b] Cc1cc(C)cc(N(CC(=O)Nc2cccc(C)c2C)S(=O)(=O)c2c(C)[nH]c(=O)[nH]c2=O)c1
[c] COC(=O)c1ccc(NC(=O)Cn2c([N+](=O)[O-])cnc2C)cc1
[d] COc1ccc(S(=O)(=O)NCCN2CCNC2=O)cc1OC
[e] Cc1ccccc1NC(=S)N(CCCN1CCOCC1)Cc1cccnc1
Answer: a. O=C(NCC1CCN(Cc2ccccc2F)CC1)Nc1cccc(Br)c1
