Task: Answer the multiple-choice question.
Query: Which drug exhibits a -0.550\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C(CNS(=O)(=O)c1ccc(Cl)cc1)OCC(=O)N1CCN(C(=O)c2ccco2)CC1
[b] O=C(CSc1nc(-c2cccs2)cc(C(F)(F)F)n1)NCc1ccco1
[c] CCN(CC)C(=O)CSc1nnc(-c2ccco2)n1N
[d] CCOc1ccc2nc(SCC3CC3(Cl)Cl)[nH]c2c1
Answer: c. CCN(CC)C(=O)CSc1nnc(-c2ccco2)n1N
