Task: Answer the multiple-choice question.
Query: Which drug has a 3.688% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COc1cccc(CNC(=O)CCCn2nc(C)c3c(C)n(-c4ccc(C)cc4)nc3c2=O)c1OC
b: COc1cc(/C=N/NC(=O)c2cccnc2)ccc1OS(=O)(=O)c1ccc(C)cc1
c: COc1ccccc1C/C(N)=N/O
d: CCCCNC(=O)c1onc(CSc2cc(C)cc(C)c2)c1C(=O)O
Answer: c. COc1ccccc1C/C(N)=N/O
