Task: Answer the multiple choice question.
Question: Which compound has a -3.221\% 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 CCN(CC)S(=O)(=O)c1cccc(NC(=O)CSc2nc3ccccc3[nH]2)c1
b CC(C(=O)Nc1ccon1)N1C(=O)c2ccccc2S1(=O)=O
c O=C(NCCc1ccccn1)c1nc(Cn2cc(Br)cn2)no1
d C/C=C/c1ccc(OCC(O)CNCC(c2ccc(OC)cc2)N(C)C)c(OC)c1.O=C(O)C(=O)O
e C/C(=N\NC(=O)CC1N=C(Cc2ccccc2)NNC1=O)c1ccc(Br)cc1
Answer: a. CCN(CC)S(=O)(=O)c1cccc(NC(=O)CSc2nc3ccccc3[nH]2)c1
