Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.385\% 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] CCc1noc(C)c1C(=O)N1CCN(S(=O)(=O)c2cccs2)CC1
[b] O=C(Cn1cc[n+](CC(=O)c2ccccc2)c1)c1ccccc1.[Br-]
[c] CCNC(=O)COC(=O)c1cc(S(=O)(=O)N2CCCc3ccccc32)ccc1Cl
[d] O=C(c1csc2c1CCCC2)N1CCN(c2ccccc2)CC1
[e] COc1ccc(/C=C2\SC(=S)N(CCC(=O)N(CCO)c3ccccc3)C2=O)cc1OC
Answer: d. O=C(c1csc2c1CCCC2)N1CCN(c2ccccc2)CC1
