Task: Answer the multiple choice question.
Query: Which drug exhibits a 18.544\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCCCNC(=O)COC(=O)c1ccccc1F
[b] O=C(NCc1ccco1)c1cccnc1-c1nc2ccccc2s1
[c] O=C1c2ccccc2C(=O)N1S(=O)(=O)c1ccccc1
[d] S=C(NCc1ccco1)N1CCN(c2ccccn2)CC1
Answer: d. S=C(NCc1ccco1)N1CCN(c2ccccn2)CC1
