Task: Answer the multiple-choice question.
Question: Which drug has a -4.125\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. COc1ccc(C(=O)CCC(=O)N2CCN(c3cc(C)ccc3C)CC2)cc1
b. O=C(CSc1nnc(COc2ccccc2Cl)o1)NC(=O)NC1CCCC1
c. CNC(=S)Nc1cccc2[nH]ncc12
d. O=C(/C(Br)=C/Nc1cc(Cl)ccc1Cl)C(F)(F)F
e. CC(=O)Nc1ccc(N2N=C(C)C(N=Nc3ccccc3)C2=O)cc1
Answer: a. COc1ccc(C(=O)CCC(=O)N2CCN(c3cc(C)ccc3C)CC2)cc1
