Task: Answer the multiple choice question.
Question: Which drug exhibits a 15.522\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CCc1cccc(C)c1NC(=O)CC(C)(C)CC(=O)O
b: CSc1nsc2nc(=O)c(/C=C3\C(C)=Nc4ccc(C)cc43)c(N)n12
c: O=c1[nH]c(=O)n(-c2ccccc2Cl)c(O)c1C=NCCN1CCCCC1
Answer: a. CCc1cccc(C)c1NC(=O)CC(C)(C)CC(=O)O
