Task: Answer the multiple-choice question.
Query: Which drug exhibits a 16.718\% 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: CC(C)(C)OC(=O)N[C@@H](Cc1ccccc1)c1nnc(SCC(=O)O)o1
b: CC(=O)NS(=O)(=O)c1ccc(N/C(N)=N/c2nc(C)cc(C)n2)cc1
c: CC(C)Sc1cc(N2CCOCC2)nc(-c2ccc(Cl)cc2)n1
d: CC(=O)c1ccc(N2C(=NC(=O)C3CCCCC3)SC3CS(=O)(=O)CC32)cc1
Answer: c. CC(C)Sc1cc(N2CCOCC2)nc(-c2ccc(Cl)cc2)n1
