Task: Answer the multiple choice question.
Query: Which drug has a -12.820\% 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] COc1ccc2c(COC(=O)CC3Sc4ccccc4NC3=O)cc(=O)oc2c1
[b] O=C(CSc1nnc(NCc2ccccc2)s1)N1CCOCC1
[c] NC(=O)c1cc([N+](=O)[O-])ccc1NCc1cccc(N)c1
[d] Cc1c(C(=O)Nc2ccccn2)sc2nc3n(c(=O)c12)CCC3
[e] O=S(=O)(c1ccc(Cl)cc1)N1CCN(C2CCCCCC2)CC1
Answer: a. COc1ccc2c(COC(=O)CC3Sc4ccccc4NC3=O)cc(=O)oc2c1
