Task: Answer the multiple-choice question.
Query: Which compound has a -28.568\% 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(NCCc1ccccc1)C(c1cccs1)N(C(=O)c1csnn1)C1CC1
[b] COc1cc(OC)nc(-n2ncc(Br)c(Br)c2=O)n1
[c] COc1ccc(CCN=Cc2c(C)[nH]n(-c3ccc([N+](=O)[O-])cc3)c2=O)cc1OC
[d] CC(C)[C@H](NC(=O)c1ccc(F)cc1)C(=O)NC1=NCCS1
[e] Cn1ccnc1C(O)(c1nnc(-c2ccccc2)o1)C(F)(F)F
Answer: a. O=C(NCCc1ccccc1)C(c1cccs1)N(C(=O)c1csnn1)C1CC1
