Task: Answer the multiple choice question.
Query: Which compound has a 20.640\% 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) Cc1ccccc1C(=O)OC(C)CN1CCN(C)CC1.Cl
(b) Cc1ccc(S(=O)(=O)N/N=c2\sc3ccccc3n2C)cc1
(c) O=C(NC1CCCC1)C(c1ccncc1)N(C(=O)c1csnn1)c1cccc(F)c1
(d) O=C(NCc1ccccc1Cl)c1nnc(CS(=O)(=O)c2ccccc2)o1
(e) O=C(CNC(=O)c1cccs1)c1ccc(Br)cc1
Answer: e. O=C(CNC(=O)c1cccs1)c1ccc(Br)cc1
